Abstract:

　 In order to remove copper ion and nickel ion from the water more effectively , the adsorbing effects on copper ion and nickel ion of the three kinds of adsorbent chitosan , peat and marine algae had been studied.Meanwhile , it also made a study about the effects on the adsorption rate of copper ion and nickel ion of the pH of solution, adsorption time , mass concentration of adsorbent and mass concentration of metal ion.The results show that the effect on adsorbing copper ion of the chitosan is the best and the adsorption rate can even reach 98 % when the chitosan is under such conditions that pH is 6, mass concentration of adsorbent is 3 g/L and the adsorption time is 120 minutes .And the effect on adsorbing nickel ion of the peat is the best and the rate of adsorption is 80 %w hen the peat is under such conditions that pH is 6 , mass concentration of adsorbent is 1 g/ L and the adsorption time is 120 minutes .

摘要： 　为了更有效地去除水中的Cu^{2 +}和Ni^{2 +,}采用壳聚糖、泥炭和海藻3 种吸附剂对Cu^{2 +}和Ni^{2 +}进行吸附性能研究。考察了溶液pH 、吸附时间、吸附剂的质量浓度和金属离子的质量浓度对Cu^{2 +}和Ni^{2 +}吸附率的影响。结果表明, 采用壳聚糖作为吸附剂, pH 为6 , 吸附剂的质量浓度为3 g/ L, 吸附时间120 min 的条件下, 对Cu^{2 +}的吸附效果最好, 吸附率可达98% 。采用泥炭为吸附剂在pH 为6 , 吸附剂的质量浓度为1 g/ L, 吸附时间为120 min 时, 对Ni^{2 +}的吸附效果最好, 吸附率达80 %。
