| 摘 要： | 以甲醛、环氧氯丙烷为交联剂,合成了交联壳聚糖.研究了交联壳聚糖对Cu2+、Zn2+、Cr3+的吸附性能,考察了pH值、用量及金属离子初始浓度对交联壳聚糖吸附性能的影响.结果表明,交联壳聚糖对Cu2+、Zn2+、Cr3+具有较好的吸附效果,交联壳聚糖对金属离子的吸附率可达到90%以上.

| Abstract: | The cross-linked chitosan was prepared by formaldehyde and epichlorohydrin.The adsorption of cross-linked chitosan towards Cu2 ,Zn2 ,Cr3 was studied.The effects of pH,dosage and initial concentration of metal ion on the adsorption characteristics of cross-linked chitosan were studied.The results show that the cross-linked chitosan was an effective treating-reagent of removing metal ion in wastewater.The highest removal rate of metal ion was above 90%. |
