녹비작물로서 녹비보리와 헤어리베치를 환원하고, 토양개량제로서 charcoal을 시용하여 생강연작 재배지에서 생강을 재배한 결과, 토양 pH가 시험 전 6.9~8.1에서 수확 후 6.8~7.6로 감소하였으며, 전기전도도(electrical conductivity, EC)는 한 시험 전 0.45~1.25dS m-1에서 수확 후 0.30~0.61dS m-1로 감소하였다. 토양유기물(soil organic matter, SOM) 함량과 토양 중 총질소(total-nitrogen, T-N) 함량은 증가하였다. 유효인산 함량과 치환성 K, Ca, Mg 함량은 유의성 있는 차이가 나타나지 않았다. 그러나, 토양 pH를 중성화시키고, EC 경감, SOM과 T-N 함량의 증가는 토양 화학성 변화에 있어 긍정적으로 평가할 수 있다. 생강양분의 함량적 차이를 정상근과 이병근의 함량 차이, 토양의 점토함량 별 양분 함량 차이로 조사한 결과, 유의성이 있는 결과를 얻었으며, 처리구별로 차이가 있는 것으로 나타났다. 특히, 망간(manganese, Mn)의 경우, 이병근의 지하부에서 3~4배 정도 높은 것으로 나타났는데, 망간(Mn)은 식물 뿌리에 대한 독성 작용으로 뿌리를 갈변시키고 균열을 일으키는 것으로 보고된바, 뿌리썩음병의 발생으로 Mn이 작용하여 이병근의 Mn 함량이 높은 것으로 보인다. 따라서, 뿌리썩음병과 Mn의 상관관계를 밝히는 추가 연구가 필요할 것으로 판단된다. 또한, 생강 수확 후 생강 생육 상태와 생산량을 조사한 결과, 녹비보리, 헤어리베치, 녹비보리+charcoal, 헤어리베치+charcoal을 처리한 시험구(Plot 2, Plot 3, Plot 4, Plot 5)에서 생강의 생육상태가 양호하고 생산량이 높아 병발생률이 상대적으로 낮게 나타났다. 특히, Plot 4(헤어리베치+charcoal)-LCC에서는 100%의 생산량을 보였다. 녹비작물과 charcoal의 처리가 생강 생육과 생산에 있어 긍정적인 영향을 미친 것으로 판단된다. 그리고, 상대적으로 점토함량이 낮은 처리구가 점토함량이 높은 처리구보다 생육 상태와 생산량에서 우세하였는데, 모래와 점토 함량 차이에 따른 배수와 토양의 수분보유력이 생강생육에 큰 영향을 준 것으로 판단된다. This study was conducted to investigate ginger growth and its nutrient uptake depending on changes of soil properties as affected by applications of green manure crop and/or charcoal in continuous cropping system. The green manure crops applied were barley and hairy vetch, and charcoal was additionally treated in selected plots as a soil conditioner. Experimental plots were prepared as Plot 1 (control), Plot 2 (barley of 8kg 10a-1), Plot 3 (hairy vetch of 12kg 10a-1), Plot 4 (charcoal of 1,000kg 10a-1 and barley 8kg 10a-1), and Plot 5 (charcoal of 1,000kg 10a-1 and hairy vetch of 12kg 10a-1) with two different soil conditions (high clay content, HCC and low clay content, LCC). When comparing selected chemical properties of soils before and after cultivating ginger plant, soil pH decreased from 6.9~8.1 to 6.8~7.6, and electrical conductivity (EC) also declined from 0.45~1.25 dS m-1 to 0.30~0.61 dS m-1. However, the content of soil organic matter (SOM) and total nitrogen (T-N) increased. Thus, the soil chemical properties were improved with the applications of green manures and charcoal. Also, macro- and micro-nutrient contents of ginger plants in the different plots were various between normal and diseased plants grown in soils with HCC and LCC. In particular, the concentration of manganese (Mn) was 3~4 folds higher in the diseased plant than in the normal plants. Ginger growth status and yield was relatively improved with the applications of green manures and charcoal as comparing with control plot. Especially in the Plot 4 with LCC, the ginger plant was not infected by root-rot disease.

윤봉기,박인진,유영권,허원영,김병운,김용웅 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.3

양파재배 토양에서 토양개량용으로 적합한 목탄의 원료 수종을 선발하기 위해서 관행(무처리)과 코코넛피트, 대나무, 참나무, 활엽수 수피, 소나무로 만든 목탄분말의 6처리로 시용량 500㎏· 10a^(-1)으로 하여 2002년에 시험한 결과는 다음과 같다. 1. 시험에 사용한 5종 목탄의 pH는 5.1~10.1, T-N 0.15~0.71%, P₂O_(5) 2.06~2.65%, K₂O 0.20~0.86% 범위였으며 1 ㎜이하 입자의 분포는 9.0~84.8%이었다. 2. 양파의 생육은 목탄시용으로 줄기직경이 크고 주당 엽수가 많은 경향이었으며 참나무, 활엽수 수피, 대나무 목탄처리 구에서 생육이 좋았다. 양파의 수량은 4,631~5,114㎏ 10a^(-1)으로 무처리(4,638㎏)에 비하여 구고가 크고 구중이 무거운 참나무목탄과 활엽수 수피 목탄처리구에서 각각 10%, 소나무 목탄구에서 3% 증수되었으며 유의성이 인정되었다. 3. 시험 후 토양의 물리성은 목탄 시용으로 용적밀도와 토양의 고상비율이 줄어들 고 액상과 기상, 공극율이 증가하는 경향을 보였다. 화학성은 코코넛 피트처리구 를 제외한 처리구에서 토양 pH가 개선되었고, OM, CEC 는 모든 처리구에서 증가하는 경향을 보였다. This experiment was conducted to find out moderating tree kinds of wood charcoal pow-der for soil improvement and onion growth in 2002 year. The wood charcoal materials were coconut peat, bamboo, black oak, pine, and broadleaf tree bark. Wood charcoal application rate was 500 ㎏ 10a^(-1). Results were summerized as follows; Chemical properties of wood charcoal used experiment were pH 5.11~10.1, T-N 0.15~0.71%, P₂O_(5) 2.06~2.65% and K₂O 0.20~0.86%. The particle size of <0.1 ㎜ was 9.0~84.8%. Onion growth of plot applied wood charcoal was better than that of plot not applied wood charcoal. The number of leaf and diameter of stem at plot applied wood charcoal was better than that of plot not applied wood charcoal. Growth of plot applied black oak charcoal, broadleaf tree bark char-coal, and bamboo charcoal was better than that of any other plot. Yield of plot applied wood charcoal was 4,631~5,114 ㎏ 10a^(-1). The yield of plot applied black oak charcoal, broadleaf tree bark charcoal and pine charcoal was increased 10, 10, 3% than that of control(4,638 ㎏ 10a^(-l)), respectively. It was significant at 5% level. Soil physical properties of after experiment was decreased bulk density and solid phase, but liquid phase, air phase and porosity were increased than that of control. Soil chemical properties of after experiment trend to be improved pH. Soil OM and CEC was increased than that of control.

국산수종으로 탄화한 목탄의 물성 및 흡착성

조태수(Tae-Su Jo),이오규(Oh-Kyu Lee),안병준(Byung-Jun Ahn),최준원(Joon-Weon Choi) 한국산림바이오에너지학회 2006 산림바이오에너지 Vol.25 No.1

탄화온도가 제조된 목탄의 물성에 미치는 영향을 알아보기 위하여 300~900℃에서 탄화한 국산 수종의 목탄 특성을 조사하였다. 탄화수율은 600℃까지는 급격히 감소하나 그 이상의 온도에서는 수율감소가 둔화되었으며, 탄화온도의 증가와 더불어 목탄의 pH는 증가하여 알칼리성을 나타내었다. 목탄의 열량은 600~700℃에서 최고를 나타내며, 더 높은 온도에서 탄화하더라도 열량의 증가는 보이지 않았으며, 낙엽송 목탄이 상수리 목탄보다 다소 높은 열량을 나타내었다. 또한 탄화온도의 증가에 따라 탄소함량이 증가하는 반면, 수소나 산소함량은 감소되었고, 목탄의 비표면적은 600℃까지는 탄화온도의 증가와 함께 증가하나, 그 이상의 온도에서는 감소되거나, 증가 폭이 감소된 후, 800℃ 이상의 탄화온도에서 다시 증가하는 경향이 있었다. 목탄의 흡착력을 요오드흡착량 및 초산가스 흡착력으로 조사 한 바, 탄화온도의 증가와 함께 이들에 대한 흡착성이 증가하였으며, 낙엽송 목탄이 상수리 목탄보다 다소 높은 흡착력을 나타내었다. 이상과 같은 결과로부터 탄화온도에 따라 목탄의 물성과 흡착성이 다르기 때문에 목탄의 특성을 고려하여 적정한 용도에 사용되어야 목탄 효과를 극대화할 수 있을 것으로 생각된다. Properties of wood charcoal made from the domestic wood species at 300-900℃ have investigated to understand the correlation between carbonization temperature and chemical and physical characteristics of wood charcoal. In terms of charcoal yield at particular carbonization temperatures, it was drastically decreased until the temperature reaches up to 600℃ and the decrease ratio of yield was reduced at higher temperatures. As the carbonization temperature increased, pH of the wood charcoal increased so that it became basic at last. The wood charcoal prepared at 600~700℃ showed the highest caloric value and those of wood charcoals made at higher temperature became plateau at a little lower level than the peak. The caloric value of Japanese larch charcoal was a bit higher than that of Red oak charcoal. The carbon content in the wood charcoal was increased as the carbonization temperature increased, whereas the hydrogen content was decreased. Specific surface area of the wood charcoal became larger with increase in temperature up to 600℃ but it was decreased or reduced in the increasing ratio after, and then it rose again at higher temperature than 800℃. Absorption capacity of the wood charcoal against iodine and gaseous acetic acid became greater as the carbonization temperature increased. Japanese larch charcoal presented higher absorption capacity than Red oak charcoal. As the above results, it is revealed that carbonization temperature affects the chemical and physical properties of wood charcoal. Therefore, to use wood charcoal with maximum effect it should be prepared at optimum temperature for proper use.

박영성(Yeong-Seong Park),진동섭(Dong-Seop Jin),이재헌(Jae-Hun Lee) 대전대학교 환경문제연구소 2005 환경문제연구소 논문집 Vol.9 No.-

Absorption of H₂S and physicochemical properties of charcoal was investigated using various charcoals such as hard charcoal, fine charcoal made of bamboo, and charcoal made of bamboo. The properties of various charcoal were analyzed using BET, SEM and pH meter and absorption experiment for H₂S was carried out to determine the absorption equilibrium in the batch reactor. As results of analysis for properties, the pHs were arranged in order of hard charcoal > charcoal made of bamboo > fine charcoal made of bamboo. The pH of original sample was the highest and pH of desorption sample was lower than that of absorption sample. It was also found that adsorption equilibriums of fine charcoal made of bamboo and charcoal made of bamboo were higher than hard charcoal. Therefore, fine charcoal made of bamboo and charcoal made of bamboo can be applied more efficiently than hard charcoal to remove the odor such as H₂S by adsorption in the atmosphere at the normal temperature.

신수정 ( Soo Jeong Shin ),김병로 ( Byung Ro Kim ) 한국목재공학회 2014 목재공학 Vol.42 No.4

목탄을 이용한 미네랄수의 제조가능성을 알아보기 위해, 목탄의 무기성분 용출 및 수소이온농도 및 잔류염소흡착 성능을 조사하였다. 무기성분 용출은 탄화온도가 높아짐에 따라 칼륨의 경우 용출량이 높아지나, 나머지 무기성분들의경우 차이가 적었다. 무기성분 용출량은 각 수종에서 칼륨이 가장 높은 값을 나타냈고 다음으로는 나트륨, 칼슘 순으로 나타났고, 수종 간에는 칼륨의 경우 활엽수인 굴참남무와 버즘나무가 침엽수인 소나무, 낙엽송 및 잣나무에 비하여현저히 높게 나타났고, 나머지 무기성분은 수종간 칼륨만큼 큰 차이는 없었으나 칼륨과 같은 경향을 나타냈다. 수소이온농도는 활엽수인 버즘나무(600℃의 경우 pH 8.5)와 굴참남무(pH 8.4)가 높게 나타났고, 낙엽송(pH 7.8), 소나무(pH 7.2), 잣나무(pH 7.0)가 앞의 두 수종보다 낮은 값을 나타냈다. 염소제거량은 모든 수종에서 대조구보다 높은 제거량을 나타냈고, 침엽수인 잣나무와 소나무가 활엽수인 낙엽송, 버즘나무, 굴참나무보다 높은 제거율을 나타냈다. 분말목탄과 각형목탄 간 무기성분 용출량 및 수소이온농도에서 차이가 없으므로, 목탄을 이용한 미네랄수 제조에는 분말목탄보다 제조도 용이하고, 용출 후 처리도 용이한 각형목탄이 좋을 것으로 생각된다. To evaluate wood charcoal as raw material for mineral water production, dissolution of inorganic ions from charcoal to water, pH and adsorption ability of chlorine in water were investigated as main variables. More potassium ion was dissolved in water as higher temperature manufactured charcoal but other ions showed no difference with different charcoal making temperatures. Highest dissolved cation was potassium followed by calcium and sodium. Among wood species, charcoal from Quercus variabilis and Platanus occidentalis showed significantly higher potassium content in water than that of larch, red pine and white pine. Other cations had similar pattern to the potassium but their difference was not apparent as much as potassium. pH value of water treated with charcoal was higher for wood charcoals from Platanus occidentalis (pH 8.5) and Quercus variabilis (pH 8.4) which contained higher inorganic cations. In chlorine removal in water by charcoal, all wood charcoals showed greater chlorine removal than that of the control, but softwood charcoals resulted in higher removal than those of hardwoods. There was no significant difference in the dissolution of cations and pHs between particle charcoal and whole charcoal. With easy of control, whole charcoal is better for mineral water making raw material than particle charcoal does.

이동영 ( Dong Young Lee ),김병로 ( Byung Ro Kim ) 한국목재공학회 2010 목재공학 Vol.38 No.6

국내 시판용 전통 목탄의 과학적인 성질 규명과 주요 기능성 분석과 이용 방안에 대한 분석을 실시하였다. 국내에서 구입 가능한 시판용 목탄의 범위 내에서 해부학적 특성, 원소 조성, 무기성분 조성, 발열량, 음이온 및 원적외선 방사량, 조습성 등의 분석을 통하여 기능성 재료로 이용 가능성에 대하여 판단하고자 하였다. 원소조성. 무기물 조성, 음이온 및 원적외선 방사량은 목탄 제조 방법과 제조회사에 따라서 큰 변이를 보였다. 특히 조습성은 흑탄의 경우 백탄이나 기계숯 보다 열등한 성능을 나타내었다. 전통숯을 기능성 재료로 사용하기 위해서는 해부학적 특성, 원소 조성, 무기물 조성, 발열량, 음이온 및 원적외선 방사량, 조습성을 분석하여 선핵적 이용이 필요 할 것으로 생각한다. 또한 차후 원하는 기능에 맞는 목탄 제조 방법 기술의 개발이 필요할 것으로 생각한다. We investigated the functional characteristics of commercial wood charcoal in Korea and their application as functional raw materials. The areas of analysis were anatomical features, elementary composition, mineral composition, caloric values, anion and far-infrared ray emission, and moisture absorption capacity. Based on the analyses as above mentioned, it is considered that charcoal can be evaluated as functional raw material In commercial wood charcoal in Korea, there were highly varied depending on manufacturing methods as black charcoal, white charcoal and mechanical charcoal and manufactures for elementary composition, mineral composition, anion emission, far infrared ray emission. Especially, black charcoal showed lower moisture absorption capacity than white charcoal and mechanical charcoal. For charcoal as functional raw material, selective usage are needed based on the analyses of anatomical features, elementary composition, mineral composition, caloric values, anion and far-infrared ray emission, and moisture absorption capacity. Specific charcoal making methods for improving specific functionality, required as functional raw material, are necessary in further research.

김호상 ( Kim Ho Sang ) 대구사학회 2003 대구사학 Vol.72 No.-

It is the very important part of restoring the human life of recent age that we study the Charcoal which was the most important heat energy. But the charcoal kiln of recent age has never studied because of beginning to excavate it only in these days. In this article, I considered what the stricture, location, type of the charcoal kiln was, how many types of charcoal kiln there were and what species of charcoal(wood - before being burned) there are. In this situation, after researching the typical sites which were excavated up to now, I restored its structure and then drew the sketch and arranged terms of each detailed title of the charcoal kiln. According to the types of kilns, I classified the charcoal kilns of recent age into two : a charcoal kiln built on the ground and charcoal kiln built underground. In case of a charcoal kiln built on the ground, I again classified it as 4 types and in case of a charcoal kiln built underground, I classified it as 3 types. The charcoal kiln location is possible to anywhere it has the good conditions; having convenient drainage, the proper wind direction and especially easy to gain wood. From the data that was found from the result of analyzing the charcoal material collected from inside the charcoal kiln, we came to know that wood as the kind from the oak tree was used for producing charcoal.

이나루 ( Naroo Lee ),이광용 ( Gwang Yong Yi ),박두용 ( Dooyong Park ) 한국산업보건학회 2014 한국산업보건학회지 Vol.24 No.2

Objectives: To develop domestic charcoal tubes with good adsorption capacity, breakthrough experiments were performed on four types of activated charcoal. Materials: The adsorption capacity and the adsorption rate were determined using a modified Wheeler equation after the breakthrough experiment. For four types of charcoal (J, K, S and SKC Inc. 226-01), 100 ㎎ were used in the breakthrough experiment. The test was done on benzene, toluene, n-hexane, and acetone in a dynamic chamber. Results: K charcoal had the greatest surface area and the highest micropore volume. J charcoal had a similar surface area and micropore volume to SKC charcoal. S charcoal had the lowest surface area and micropore volume. J charcoal had the highest adsorption capacity at 101, 252 and 609 ppm of benzene. The gap in benzene adsorption capacity among the types of charcoal was the least at 609 ppm and the greatest at 101 ppm. J charcoal showed the highest adsorption capacity at 54, 106, 228 and 508 ppm of toluene. J charcoal and SKC charcoal had a similar adsorption capacity for acetone. J charcoal had the highest adsorption capacity for n-hexane. In the experiment featuring 10% breakthrough volume, 10% breakthrough occurred at 18 liters at 2065.9 ㎎/㎥ for J charcoal and at 20 liters at 1771.2 ㎎/㎥ for K charcoal. It was difficult to judge adsorption capacity by surface area and micropore volume of charcoal. J charcoal, which was similar to SKC charcoal in surface area and micropore volume, showed good adsorption capacity at common workplace concentrations. Conclusions: The adsorption capacity of J and K charcoal was superior compared with SKC charcoal. J and K charcoal can be considered appropriate for use as sampling media based on this result.

오염수계 내 세슘 제거를 위한 대나무 활성탄의 흡착효율 규명

안정필(Joung pil Ahn),이민희(Min hee Lee) 대한자원환경지질학회 2018 자원환경지질 Vol.51 No.2

세슘은 물속에서 고상보다는 이온이나 착염 등 용존 형태로 존재하는 특성이 강하여, 오염 수계로부터 세슘 제거가 어려운 것으로 알려져 있다. 최근 많은 연구들이 수계 내에서 세슘의 제거효율이 높은 흡착제를 개발하는데 집중하고 있다. 본 연구에서는 대나무 활성탄을 흡착제로 사용하여 수계 내에 존재하는 세슘을 효과적으로 제거하는 실내실험을 실시하였다. 수용액으로부터 대나무 활성탄의 세슘 제거효율을 측정하고, 최적의 세슘 제거능을 가지는 흡착 조건을 도출하고자 다양한 조건에서 흡착 배치실험을 수행하였다. 국내에서 유통되고 있는 5 종류의 대나무 활성탄의 표면 특성을 SEM-EDS와 XRD 분석으로 규명하였으며, 이 중에서 비표면적이 큰 3 종류의 대나무 활성탄을 대상으로 세슘 제거 배치실험을 실시하였다. 다양한 초기 세슘 농도를 가지는 인공수(0.01 ~ 10 mg/L 범위)를 대상으로 대나무 활성탄에 의한 수용액 내 세슘 제거량을 측정하여 제거효율을 계산하였고, 두 종류의 흡착 등온식들을 흡착 배치실험결과에 대응시켜 흡착 상수값을 결정함으로서, 대나무 활성탄의 세슘 흡착 특성을 규명하였다. FE-SEM 분석 결과, 대나무 활성탄은 표면이 다수의 기공을 포함하는 대나무의 섬유질 조직을 그대로 유지하는 입자들로 구성되어, 이들 섬유질 조직 내 다양한 형태의 기공들과 엽상조직 표면들이 주요 세슘 흡착공간인 것으로 밝혀졌다. 흡착 배치실험결과, C type 대나무 활성탄의 세슘 제거효율이 가장 높았는데, 특히 수용액의 세슘 초기 농도가 1.0 mg/L 이하인 경우에도 75 % 이상(최고 82 %)을 나타내어, 원전사고 등에 의해 오염된 현장 지하수나 지표수(해수 포함)의 세슘농도가 대부분 1.0 mg/L 이하임을 고려하면, 실제 오염수 정화 가능성이 높을 것으로 밝혀졌다. 수용액의 온도는 5-15℃ 범위, pH는 3-11 범위에서 높은 세슘 제거효율이 일정하게 유지되는 것으로 나타나 다양한 오염수에 적용할 수 있을 것으로 판단되었다. 흡착 배치실험 결과는 Langmuir 흡착모델과 유사하였으며, C type 대나무 활성탄의 최대흡착농도(qₘ: mg/g)값은 63.4 mg/g으로 기존의 상용화된 흡착제 값보다 높았고, 수용액의 초기 세슘 농도가 1.0 mg/L이하인 경우 표면흡착률(surface coverage) 값도 낮게 유지되어, 적은 양의 세슘으로 오염된 수계를 효과적으로 정화할 수 있음을 입증하였다. The cesium (Cs) removal from the contaminated water system has been considered to be difficult because the cesium likes to exist as soluble phases such as ion and complexes than the solid in water system. Many researches have focused on developing the breakthrough adsorbent to increase the cesium removal efficiency in water. In this study, the laboratory scale experiments were performed to investigate the feasibility of the adsorption process using the bamboo charcoal for the Cs contaminated water system. The Cs removal efficiency of the bamboo charcoal were measured and the optimal adsorption conditions were determined by the adsorption batch experiments. Total 5 types of commercialized bamboo charcoals in Korea were used to identify their surface properties from SEM-EDS and XRD analyses and 3 types of bamboo charcoals having large specific surface areas were used for the adsorption batch experiment. The batch experiments to calculate the Cs removal efficiency were performed at conditions of various Cs concentration (0.01 - 10 mg/L), pH (3 - 11), temperature (5 - 30℃), and adsorption time (10 - 120 min.). Experimental results were fitted to the Langmuir adsorption isotherm curve and their adsorption constants were determined to understand the adsorption properties of bamboo charcoal for Cs contaminated water system. From results of SEM-EDS analyses, the surfaces of bamboo charcoal particles were composed of typical fiber structures having various pores and dense lamella structures in supporting major adsorption spaces for Cs. From results of adsorption batch experiments, the Cs-133 removal efficiency of C type bamboo charcoal was the highest among those of 3 bamboo charcoal types and it was higher than 75 % (maximum of 82 %) even when the initial Cs concentration in water was lower than 1.0 mg/L, suggesting that the adsorption process using the bamboo charcoal has a great potential to remove Cs from the genuine Cs contaminated water, of which Cs concentration is low (< 1.0 mg/L) in general. The high Cs removal efficiency of bamboo charcoal was maintained in a relatively wide range of temperatures and pHs, supporting that the usage of the bamboo charcoal is feasible for various types of water. Experimental results were similar to the Langmuir adsorption model and the maximum amount of Cs adsorption (qm : mg/g) was 63.4 mg/g, which was higher than those of commercialized adsorbents used in previous studies. The surface coverage (θ) of bamboo charcoal was also maintained in low when the Cs concentration in water was < 1.0 mg/L, investigating that the Cs contaminated water can be remediated up with a small amount of bamboo charcoal.
