현재 토양오염에 대한 관심이 점차 증가하고 있으며, 토양오염은 토양에 국한 된 오염이 아닌 대기 및 수질오염에 복합적으로 영향을 미치고 있다. 따라서 본 연구는 유류로 오염된 토양을 기존의 정화 방법에 비하여 시간적 경제적으로 많은 장점을 가지고 있는 마이크로파를 이용하여 정화 효율을 극대화시켰으며, 마이크로파를 토양에 적용하기 위하여 수분과 발열체 등을 이용하여 토양발열 효과를 증가시켜 빠른 토양정화 효율을 확인하였다. The interest of soil pollution is increasing, and soil pollution is not limited on the soil but connected to atmosphere and water system. Gas adsorption on adsorbents depends on temperatures and pressures. When these parameters are fixed, If the gas adsorption capability and selectivity can be changed. If the gas adsorption is controlled by another factor like electromagnetic field. The microwave has characteristics to excite particular components such as water without destroying it. This study maximanized the efficiency of purification using economic microwave, and improved purification of soil efficiency using water and a heating element was founded.

According to this research, the purpose is to remove or recover absorbed VOCs by activated carbon supported metal by microwave. We produced Barium hydroxide (the metal supported the activated carbon) from divided by each wt% and made experiments in SEM, electric discharge, heating and adsorption with investigating microwave. The result, the higher metal wt% activated carbon got, the lower heating in activated carbon we got and the amount of electric discharge was reduced.

According to this research, the purpose is trying to find out the emission character and ozone creation potential classified by each site of VOCs. After collecting industrial and vehicle, ambient air and air of industrial zone, make qualitative and quantitative analyses of them. FMI was discharged most from industrial, similar gasoline at vehicle and except idling an engine Aromatic materials were issued most from the LPG vehicles. Aromatic materials were also discharged most from ambient air and appeared most around the industrial area. BTEX captured a high share of aromatic compounds. BTEX was discharged at the rate of 73.4% from industrial, 72.2% from vehicle and 81.1% from the material around boundary. FMI was discharged most at the rate of 21% of the total amount of ozone creation from industrial, and similar gasoline was discharged most at the rate of 35.1% from vehicle.

This study sets control and separation recovery of VOCS as the main study purposes. Doing actively research on control and separation recovery of Present VOCS, the toluene with which this research was also adsorbed by activated carbon using the characteristic of microwave was separated. When desorbing toluene using microwave, electric discharge generates activated carbon and microwave with the electric characteristic. When electric discharge occurs, the moment temperature of activated carbon comes to rise by 5,000~10,000℃ or more, and such a rapid temperature rise causes various problems, such as danger of explosion of toluene, and weakened durability of activated carbon. Then, in this study, electric discharge was suppressed using the silica stone anhydride which is the quality of an insulator about the surface of activated carbon, and the experiment about the adsorption and the desorption of toluene by the activated carbon of improvement was conducted.

Traditional regeneration methods of activated carbon take long time to regenerate activated carbon and have economical problem. the purpose of this study is to reuse activated carbon by desorption of VOC in activated carbon. But, when microwave is irradiated to activated carbon, durability of activated carbon decrease and there is risk of fire with strong volatile VOC. so we reformed surface of activated carbon by microwave irradiation and solved these problems by control of discharge and temperature rise in optimal reformed activated carbon.
