摘要
研究了壳聚糖对Cu2+的吸附特性,考察了Cu2+的浓度、壳聚糖用量、吸附时间以及体系pH等不同的吸附条件下,壳聚糖对废水中Cu2+的吸附效果。当质量分数为0.8%的壳聚糖的用量为0.4mL,吸附时间为30min,pH为5.5～6.5时,对Cu2+浓度为0.1×10-3mol/L的去除率可达98.3%。
A new product called 'chitosan'is used to remove copper(Ⅱ) from wastewater. The effects of pH,the dosage of chitosan and copper(Ⅱ) concentration are studied. It shows that pH 5.5～6.5 is the optimal range of adsorption, when the concentration of copper(Ⅱ) is 0.1×10-3 mol/L,the dosage of 0.8% chitosan is 0.4 mL,the adsorption time is 30 min,pH is 5.5～6.5,the adsorption rate can mostly reach 98.3%.
