| Research Abstract |
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.
