摘要
利用膨润土负载壳聚糖吸附处理结晶紫染料废水,考察了pH值、搅拌时间和膨润土负载壳聚糖吸附剂的用量等对结晶紫去除率的影响。结果表明,当pH值为5,搅拌时间为30min,膨润土负载壳聚糖吸附剂投加量为500mg时,处理50mL浓度为5×10-4mol/L染料废水的结晶紫去除率达到99.5%。
This paper examined the adsorption of bentonite loading chitosan in treating crystal violet of dye wastewater, from the aspects of pH, mixing time and adsorbent dosage. The results show that the removal rate of crystal violet in 50ml dye wastewater is 99.5%, when the pH is 5, stirring time is 30min, adsorbent dosage is 50mg and the wastewater concentration is 5×10^-4 mol/L.
