The Preparation of Chitosan and its Application in the Treatment of Electroplating Wastewater

Abstract:

In this paper, the chitosan was prepared for treatment of electroplating wastewater. The influence of temperature, PH value, the amount of chitosan and mixing time on the effects of the wastewater treatment was investigated. The result showed that at PH=3, with the addition of 0.6g chitosan and 2h of mixing, the optimum wastewater treatment effect can be obtained. The removal rate of COD is above 80% and the adsorption rate of copper ion is above 99%. The decolourization ratio and the turbidity indicated that the treatment is effective.
