高分子吸着劑 微分層反應器에 依한 3,5-디메틸페놀의 吸着速度
安旼燁,鄭在灌 成均館大學校 科學技術硏究所 1997 論文集 Vol.48 No.1
In this study, in order to remove 3,5-dimethylphenol from aqueous solutions the high porous polymer resin(HY20) was employed as an adsorbent in a differential bed reactor. In differential bed tests an optimum flow rate and an overall adsorption rate were determined. At the optimum pH 7 and flow rate of 400ml/min the total deviation of overall adsorption rate was 11.10% and the overall adsorption rate was found as follows : r=0.122C^1.068_fc-(0.534×10^0.0184C_i)q_s^(0.447-0.004C_i)

In this study, in order to remove 3,5-dimethylphenol from aqueous solutions, the high porous polymer resin(HP20), weak anion exchange resin(WA30), and strong anion exchange resins(PA412, SA10AP, SA20AP) were employed as adsorbents manufactured by Sam Yang Co.. The pH effects, adsorption capacities of several adsorbents, and finally adsorption isotherms were examined. The results were as follows : 1. The high porous polymer resin(HP20) was better than other resins in the adsorption capacity and the adsorption capacity of ion exchange resins was large in order of their exchange capacities : WA30>SA10AP>SA20AP>PA412. 2. The high porous polymer resin(HP20) at pH 7, weak anion exchange resin(WA30) at pH 9, and strong anion exchange resins(PA412, SA10AP. SA20AP) at pH 11 showed their maximum adsorption capacities, respectively. 3. The Freundlich and Langmuir isotherms were matched well with experimental data in the concentration range(15-150mg/l) of this experiment.

In this study in order to remove 3,5-dimethylphenol from aqueous solutions the granular activated carbon, SLS-100, manufactured by Sam-Chul-Li Company, was used as an adsorbent. The adsorption time to reach equilibrium and the effects of activated carbon size, temperature, and pH were analyzed. Finally adsorption isotherms for various sizes of activated carbon were examined at optimum pH. 1. The adsorption capacity of activated carbon in the size range (-20∼50/60 mesh) of this study was highest at 50/60 mesh size and the equilibriium time for the adsorption of 3,5-dimethylphenol was found 10 days. 2. The maximum adsorption took place at the lowest temperature of 5℃ in the temperature range (5∼50℃) of this investigation. 3. The activated carbon (35/40 mesh) showed its maximum adsorption capacity at pH 7. 4. The Langmuir isotherm as well as the Freundlich isotherm agreed well with the experimental data in the concentration range (1∼80 mg/l) of this experiment, although the Langmuir isotherm showed a little better agreement than Freundlich isotherm.

In this study in order to remove 3,5-dimethylphenol from aqueous solutions the granular activated carbon. SLS-100, manufactured by Sam-Chul-Li Co., was employed as an adsorbent. The activated carbon (35/40 mesh) was employed in a differential bed reactor to remove 3,5-dimethylphenol from aqueous solutions at room temperature (25 ± 3℃) and at the optimum pH 7 and optimum flow rate of 421 ml/min. The resulting overall adsorption rate was found as follows: r = 0.1634 C_fc^(0.9823) - 0.1563q_s^(0.9523)
