Abstract
Biosorption of Pb and Cr by Sargassum confusum was evaluatet at in the various conditions. The uptake capacities for Pb and Cr were 197.5 mg Pb/g biomass and 133.1 mg Cr/g biomass, respectively. The adsorption parameters for Pb and Cr were determined according to the Langmuir and Freundlich model. Biosorption of Pb and Cr was increased with the increase of pH value. Pb and Cr adsorbed by S. confusum could be recovered by desorption process with 0.1 M HCl, 0.1 M
우리나라 인근 해역에서 가장 쉽게 채취할 수 있는 해조류 중의하나인 S. confusum을 이용한 Pb 및 Cr의 생체홉착 실험을 수행하였다. 두 중금속 모두 흡착 평형에는 15분 안에 도달하였으며, 평형 흡착량은 각각 197.5mg Pb/g biomass 및 133.1mg Cr/g biomass이었다. Pb 및 Cr의 생물학적 흡착은 Langmuir모델에 더 잘 적용되었다. Pb 흡착시에 Ca가 500mg/L 존재하여도
