| 摘 要： | 以蟹壳为原料探讨壳聚糖的生产条件，分别研究了壳聚糖作为吸附剂和絮凝剂对水中重金属离子及模拟印染废水的处理效果．研究结果表明，蟹壳种类不同，制备工艺中所需的酸碱浓度及处理时间也不一样．在静态条件下，体系的ｐＨ值、吸附时间、壳聚糖用量和金属离子浓度对壳聚糖的吸附性能有较大影响．在最佳条件下壳聚糖对Ｐｂ２＋ 、Ｃｒ（ＶＩ）、Ｃｕ２＋ 的吸附去除率均可达到９８％ 以上．在ｐＨ值为４～５时，壳聚糖对ｒａｆａｆｉｘ ｒｅｄ 和ｍ ａｔａｆｉｘｂｌｕｅ 两种染料模拟废水的色度去除率也可达到９５％ 以上．

| Abstract: | This paper discusses the productive condition of chitosan with crab shell as material and the effect of absorption,as absorbent,to wastewater with heavey metal ions under static condition ,and the effect of coagulation,as coagulant,to dyeing wastewater.The result shows that pH of the system and absorb time effect significantly on absorption properties of chitosan.Using chitosan with the optimum condition,the removal percentage of Pb 2 ,Cr(VI),Cu 2 can reach above 98. |
