摘　　要：采用壳聚糖(CTS)对K_2Cr_2O_7中的Cr^(6+)离子进行吸附,探讨了pH值、铬离子浓度和吸附时间对吸附性能的影响,得出了CTS对Cr^(6+)离子吸附适宜的工艺条件。In this paper, chitosan（CTS） was used to adsorb Cr^6＋ ion in K2Cr2O7, and effect of pH value, concentration of chromium ion and adsorption time on the adsorption performance was discussed. The suitable technological conditions for Cr^6＋ ion adsorption of CTS were obtained.
