本文对壳聚糖ＣＨＴ吸附Ｃｒ（ＶＩ）的条件，吸附选择性进行了研究。研究结果表明，ＣＨＴ质子化后吸附的最佳条件是Ｃｒ（ＶＩ）溶液ｐＨ３～４；吸附平衡时间１０～１２小时；Ｃｒ（ＶＩ）浓度不大于６０ｍｇ·Ｌ－１
In this paper, chitosan CHT adsorption Cr (VI) conditions, adsorption selectivity was studied. The results showed that the optimum conditions of CHT protonation adsorption were pH3 ~ 4 of Cr (VI) solution, adsorption equilibrium time of 10 ~ 12 hours, and concentration of Cr (VI) of not more than 60 mg · L-1
