摘要
制备了两种交联壳聚糖吸附剂CCTS及其还原产物H-CCTS,研究了它们对Cu2+、Zn2+、Cd2+的吸附性能,考察了pH值、吸附时间等因素对吸附性能的影响。结果表明H-CCTS有较好的吸附性能,对Cu2+、Zn2+、Cd2+的吸附容量分别为:129.64、106.642、10.03 mg/g。
Two different modified chitosan CCTS and H-CCTS were prepared by cross-link reaction.The adsorbents are investigated in relation to their adsorption behavior for Cu^2+、Zn^2+、Cd^2+,as well as the effect of pH and time.The result indicates that the H-CCTS had higher adsorption capabilities than CCTS,the H-CCTS had adsorption capabilities of 129.64、106.64、210.03 mg/g for Cu^2+、Zn^2+、Cd^2+.
