Abstract
In this study, we conducted a combined adsorption-sequential extraction analysis(CASA) to investigate temperature effects of single adsorption of lead, copper, zinc and cadmium on natural clays. As a result, it was found that in a single adsorption of lead and copper, about 50% of adsorption was occluded in carbonate phase, and in case of cadmium, about 80% of adsorption was occluded in exchangeable phase. At temperature below
본 연구에서는 자연점토에 납, 구리, 아연, 카드뮴의 단일 흡착 시 온도변화에 따른 흙의 구성성분별 흡착거동을 살펴보기 위해 혼합 흡착-연속추출법(combined adsorption-sequential extraction analysis, CASA)을 사용하였다. 실험결과 납과 구리의 경우 약 50%이상의 분배가 탄산염 형태로 나타났고, 카드뮴의 경우 약 80%이상의 분배가 이온교환 형태로 나타났다. 아연의 경우
