한국산(韓國産) 천연(天然) zeolite에 양이온 계면활성제(界面活性劑)인 TMA(Tetrametyl ammonium)를 흡착시킨 TMA-zeolite complex로 수용액 중의 휘발성 유기화합물인 benzene을 흡착시켜 제거하는 실험을 행하였다. 천연 zeolite의 CEC는 95.9 cmol/kg이었고, X-선 회절분석과 IR분석 결과 clinoptilolite와 mordenite가 주성분이었다. TMA는 zeolite표면에 CEC의 약 8% 정도가 신속히 흡착되었으며 이와 같이 TMA를 흡착한 TMA-zeolite complex에 의하여 수용액중의 benzene이 효과적으로 제거(除去)되었다.
This study was performed to remove the dissolved benzene in water by using TMA-Zeolite complex which was formed by the adsorption of TMA(Tetramethyl ammonium), a kind of ration surfactant on a natural zeolite produced in Korea. The dorminant clay minerals of the natural zeolite was identified by X-ray diffractometry and Infrared spectrophotometry to be mordenite and clinoptilolite. The CEC of the zeolite used was 95.9 cmol/kg. TMA was adsorbed on natural zeolite very quickly, and the amount of TMA adsorption on zeolite was known to be equivalent to about 8% of the CEC of natrual zeolite. The amount of benzene adsorption on TMA-zeolite complex was much more than natural zeolite, indicating that the dissolved benzene in water could be removed effectively by TMA-zeolite comple.
