Abstract

In this study, cow tibial from cow bone, a kind of beef waste, sintered at $800\sim850^{\circ}C$ for three hours was used to measure its removal capacity for metal ions such as Pb, Cd and Zn in a single and a multi-component equilibrium systems. The sorption equilibrium data were analyzed as measured by the effect of media on lead, cadmium and zinc sorption. This analysis shows that the sorption of metal ions for multi-component systems applying IAST can be predicted more reasonably by the Freundlich and the Sips theory than the Langmuir.

본 연구에서는 음식업소 등에서 발생하는 폐기물의 일종인 폐 소뼈를 고온인$800^{\circ}C\sim850^{\circ}C$에서 3시간 소결시켜 담체로 제조한 후 중금속 제거제로 이용하여 납(Pb), 카드뮴(Cd), 아연(Zn)등의 중금속에 대한 단일 및 다성분계 흡착제거 관계에 대하여 일련의 실험을 수행하였다. 담체의 납과 카드뮴 그리고 아연의 제거능력을 정량화하여 흡착평형데이터를 해석하였다. 흡착평형데이터를 IAST에 적용하여 해석한 결과, Freundlich식과 Sips식이 Langmuir식보다 중금속 흡착 평형식에 잘 부합됨을 알 수 있었다.
