摘　　要：研究了壳聚糖吸附水中Ｐｂ^(２＋)，Ｃｒ^(３＋)，Ｎｉ^(２＋)，Ｚｎ^(２＋)，Ｃｕ^(２＋)的最佳条件及洗脱和再生方法。结果表明，静态饱和吸附量分别为Ｐｂ^(２＋)：８３．８ｍｇ·ｇ^(－１)；Ｃｒ^(３＋)：３２．７ｍｇ·ｇ^(－１)；Ｎｉ^(２＋)：６５．７ｍｇ·ｇ^(－１)；Ｚｎ^(２＋)；６１．０ｍｇ·ｇ^(－１)；Ｃｕ^(２＋)：６５．０ｍｇ·ｇ^(－１)．利用壳聚糖处理印染厂含Ｐｂ^(２＋)废水，效果很好。此处理方法不影响水的本底浓度，是含重金属离子废水处理的一种价格便宜、操作简单的方法。The optinial conditions of adsorbing Pb2+,Cr3+,Ni2+,Zn2+,Cu2+ by chitosan and themethods of eluting heavy metals and reproducing chitosan were investigated.The static ad-sorbing capacities respectively are 83.8mg·g-1 for Pb,32.7mg·g-1 for Cr,65. 7mg·g-1for Ni,61.0nig·g for Zn and 65.0mg·g-1 for Cu。The effect was well to treat Pb2+wastewater by chitosan in printing and dyeing mill.This method did not affect backgroundconsistency,it is cheap and simple to treat the wastewater containing heavy metal ions。
