Abstract

In this study, we conducted a combined adsorption-sequential extraction analysis(CASA) to investigate temperature effects of single and competitive adsorption of zinc and copper on natural clays. As a result, it was found out that in a single adsorption of zinc, the adsorption was mostly in the exchangeable phase, with increase n temperature. In a competitive adsorption of zinc, this trend was so strong that the exchangeable phase adsorption increase up to 80~90%. On the other hand, about 50% of copper was adsorbed in the carbonate occluded phase in single and competitive adsorptions. In the single adsorption the adsorption of carbonate occluded phase increased by 5% with the temperature increase and in the competitive adsorption the increase rate is about twice. The adsorption of zinc and copper on natural clays is an endothermic reaction with the exception of exchangeable phase adsorption.

본 연구에서는 자연점토에 대한 구리 흡착 및 구리와 아연의 경쟁 흡착 시 온도변화에 따른 흙의 각 구성성분별 흡착거동을 살펴보기 위해 혼합 흡착-연속추출법(combined adsorption-sequential extraction analysis, CASA)을 사용하였다. 실험결과 중금속 아연의 경우 농도에 따른 차이는 있지만 온도증가에 따라 주로 이온교환 형태로 흡착되는 것을 알 수 있고, 구리와 경쟁흡착의 경우 이러한 경향은 더욱 커져서 약 80~90%정도가 이온교환형태로 흡착되어진다. 반면 구리의 경우 실험을 수행한 거의 모든 농도 범위에서 약 50%이상이 탄산염 형태로 흡착되어진다. 탄산염형태로의 흡착 양상은 단일 흡착의 경우 온도증가에 따라 약 5% 증가하는 경향을 보이고, 경쟁흡착의 경우에는 약 10%정도 증가하는 경향을 나타내었다. 그리고 자연점토에서의 아연과 구리의 각 구성성분 별 흡착거동은 이온 교환 형태로 분배되는 경우를 제외하고는 온도증가에 따라 흡착량이 증가하는 흡열반응$(\DeltaH0>0)$인 것으로 나타났다.
