As(V) wastewater treatment by bioreactor using marine microalgae

用海带属废弃物处理模拟海水中的As（V）。当As（V）初始浓度较高时，该菌吸附As（V），当As（V）初始浓度较低时，该菌排放As（V）。XAFS分析表明，海带对As（V）以有机砷的形式吸附。该吸附剂从钴镍混合溶液中选择性吸附铝。这些结果表明，利用海带可以从废水中回收钴和镍。

Treamtnet of As(V) in a simulant marine water was investigated using wasted genera Laminaria. It adsorved As(V) when the initial As(V) concentration was high, whereas it discharged As(V) when the initial As(V) concentration was low. XAFS analysis showed that As(V) was adsorved in the form of organoarsenic by it. Recycling of metals from wastewater was also investigated using wasted genera Laminaria. Al was selectively adsorved by it from mixed solution of Co and Ni. These results suggested that Co and Ni could be recycled from wastewater using benera Laminaria.
