Abstract

Not only Cr(VI) is very toxic, but also it is a major pollutant in soil and groundwater. Thus Cr(VI)-containing wastewater must be treated before being discharged into the environments. Recently, biosorption technology using abundant biomass has been considered as an innovative one for removing Cr(VI) from aqueous solution. In this review article, current research and future works on Cr(VI) biosorption were widely described. Particularly, the removal mechanism of Cr(VI) by biomass was described in detail, which has been misunderstood by many researchers until now.

6가 크롬은 매우 유독한 중금속이면서도 토양 및 지하수의 주요 오염물질 중 하나이다. 따라서 6가 크롬을 함유한 폐수는 자연계에 방류되기 전에 반드시 처리되어야 한다. 이를 위한 한 가지 방법으로 자연계에 풍부하게 존재하는 바이오매스를 이용해 6가 크롬을 제거하는 기술이 최근에 주목을 받고 있다. 즉, 이번 총론에서는 바이오매스에 의한 6가 크롬의 제거에 대한 현재까지의 연구 상황 및 향후의 연구 방향에 대해 살펴 보았다. 특히, 이 분야에서 종종 실수하고 있는 부분에 대해 상세히 다룸으로써 관련 연구자들에게 도움을 주고자 하였다.
