膨润土负载壳聚糖处理含镉废水的实验研究
Experimental Study on Dispose of Cadmium Wastewater with Chitosan Loaded Bentonite
摘要
Abstract
The composite adsorbent of chitosan loaded bentonite was made with the raw material of 90%deacetylation degree chitosan to adsorb Cd2+in the solution of cadmium wastewater.This paper discussed the impact of chitosan capacity,PH value,adsorption time,additive amount of adsorbent,and Cd2+ initial mass concentration on removal rate.The result shows that when the initial mass concentration of model cadmium wastewater is 10 mg/L,the removal rate of Cd2+ will be over 94% under the condition that the mass ratio of bentonite and chitosan reaches 1∶0.03,the additive amount is 8 g/L,pH is 6,and the absorption time is 50 min.After regeneration treatment,the adsorbent can be recycled for 4 times.关键词
