생물흡착현상을 이용한 중금속오염폐수 처리기술 개발을 위한 기초연구로서 중금속흡착능이 있는 것으로 알려진 U. pinnatifida, E. stolonifera, Laminaria sp., G. amansii 등 4종의 해조류를 대상으로 중금속 흡착 특성을 조사하였다. Fig. 6. Heavy metal uptake efficiency difference with adsorption-desorption repetition.해조류 종류별 중금속 흡착능력은 U. pinnatifida≥E. stolonifera≥Laminaria sp.>G. amansii 순이었으며, 중금속 100 mg/ℓ 농도에서 Pb는 93～99% 정도 흡착이 되었고, Cu와 Cd는 70～80% 정도 흡착되었다. CaCl2을 이용하여 해조류의 작용기를 치환함으로서 중금속 흡착 및 탈착성능이 개선되었으며, 온도와 pH에 따른 중금속 흡착 변화는 큰 차이가 없었다. U. pinnatifida의 중금속 흡착은 Freundlich 흡착등온식 보다는 Langmuir 흡착등온식에 잘 일치하였고, Cu, Cd 및 Zn에 비해서 Pb가 상당히 흡착친화도가 큰 것으로 나타났다. U. pinnatifida의 중금속별 흡착효율은 다성분계 중금속일 때가 단성분계일 때 보다 감소하였으며, 탈착제로서 NTA를 처리하였을때 흡착된 중금속의 탈착효율이 가장 높았다.
Abstract
The characteristics of heavy metal biosorption on the seaweeds were investigated to develop a biological treatment technology for wastewater polluted with heavy metals. The heavy metal biosorption on seaweeds ranked in the following order: U. pinnatifida≥E. stolonifera≥Laminaria sp.>G. amansii. The Pb was biosorbed in the range of 93～99%, and the Cu and Cd were biosorbed in the range of 70～80% at the concentration of the heavy metal of 100mg/ℓrespectively. The seaweed which was pretreated with CaCl2 solution improved the biosorption of the heavy metals. The temperature and pH didn’t affect the biosorption of heavy metals. The Langmuir isotherm reasonably fit the data of heavy metal biosorption compared to the Freundlich isotherm. The affinity of metals on the biosorption ranked in the following order: Pb>Zn>Cu>Cd. The biosorption efficiency of the heavy metals on the U. pinnatifida decreased in the multi-component rather than the single component. The heavy metals adsorbed on the U. pinnatifida were recovered using 0.3%-NTA. U. pinnatifida among the seaweed used in this work showed the best performance for the biosorption of the heavy metals.
