| 摘 要： | 文章采用共混沉降法制成了石英砂．壳聚糖吸附剂，考察了石英砂．壳聚糖吸附剂对模拟含镍废水中的Ni2＋静态吸附效果的影响因素。正交实验结果表明，在壳聚糖与石英砂质量比为0．06、吸附剂加入量为12g／L、模拟含镍废水Ni2＋初始质量浓度为40mg／L、pH为7、吸附时间为40rain的条件下，Ni2＋去除率可达97．2％。

| Abstract: | In the paper,the quartz-chitosan adsorbent was made by co-mixing sedimentation method.Then orthogonal experiments were designed to investigate influencing factors while using this quartz-chitosan adsorbent for Ni2+ static adsorption in the analogous waste water containing nickel.And the results showed that the removal ratio of Ni2+ could achieve 97.2 % when the conditions below were met simultaneously:the ratio of chitosan to quartz should be 0.06;the adsorbent was added until its concentration reached 12 g... |
