Abstract

Copper and iron ions are common heavy metal ions in industrial wastewater, pollution can be caused by the direct emissions of wastewater to the environment, only when waste water reach the standard that it can be let out. Zeolite cross-linked chitosan composite adsorbent using natural raw materials, reduce the copper and iron ion content in industrial waste water by physical adsorption. The composite adsorbent made of by zeolite cross-linked chitosan (5:1) is prepared by this experiment. The adsorbent in neutral liquids under room temperature, copper iron adsorption rate was 15.8%, and the iron ions adsorption rate was 65.5%.Electroplating factory and smelters electrolytic workshop produce a large amount of wastewater containing copper, iron, if not handled pollution to living environment will be caused. In recent years, the concentration of the dispose of copper iron in wastewater is to look for more suitable, new low-cost adsorption material.
