HEAVY METAL ABSORBENT AND METHOD FOR REMOVING HEAVY METAL USING THE SAME

摘要

PURPOSE: Heavy metal absorbent and a method for eliminating heavy metals using the same are provided to cost effectively eliminate heavy metals from wastewater and to improve the quality of water by eliminating cadmium and lead from the wastewater. CONSTITUTION: A method for eliminating heavy metals using heavy metal absorbent includes the following: epiphyte and epizona attached on the surfaces of brown algae are eliminated from the brown algae; the brown algae is dried, pulverized, and mixed; the mixed algae is re-dried; heavy metal absorbent(30) containing the pre-treated brown algae is introduced into wastewater containing heavy metals; the wastewater is stirred to generate a heavy metal absorbing reaction; and the absorbent absorbing heavy metals is precipitated to be eliminated. The brown algae are either laminaria japonica or ecklonia sp..
