초록
Biosorption process is an economic and potential process for metal sequestering from the water. The oxidized Undaria pinnatifida by nitric acid had high uptake capacity for heavy metals of 4 - 6 meq / g dry mass. For the application of oxidized Undaria pinnatifida, recovery of metal in plating wastewater was studied. The uptake capacity of the oxidized Undaria pinnatifida was high compared to the ion exchanger IR-120 plus. The treatment efficiency of chromium and copper in the wastewater was 85% In batch. Activated carbon was used to assist the recovery of water by removing organic matters of the wastewater.
