| 摘 要： | 使用壳聚糖和改性壳聚糖吸附法分别处理含铬(Ⅵ)模拟废水。研究了吸附剂用量、吸附时间、废水酸度及铬(Ⅵ)离子初始浓度等对铬(Ⅵ)离子去除率的影响。并探讨不同壳聚糖的吸附效果。实验表明，Na2S改性后的壳聚糖对Cr(Ⅵ)吸附效果最为理想。该法简便，去除率高。

| Abstract: | The absorption treatment of containing chromium wastewater by chitosan and modified chitosan was studied.The influences of chitosan quantity,absorption time,wastewater's acidity,initial Cr(VI)concentration of wastewater and difietent type of chitosan on the absorpting effect of chromium were observed. The results showed that the efiect of treating waste chrome liquor with modined chitosan by Na 2S was very good. |
