摘要
将壳聚糖(CTS)与自制的丙酮酸化壳聚糖(P-CTS)、巯基化壳聚糖(CTS-SH)作为吸附剂,研究了不同吸附剂对污染水体同一金属离子的静态吸附和动态吸附及对混合金属离子的竞争吸附.分析了pH值、温度、吸附时间对吸附量的影响,研究了流速对动态吸附和脱附的影响及洗脱剂、活化剂对吸附剂复原的作用.为用壳聚糖复合物(CTS-X)清除污染水体中金属离子作了基础研究.
Take Chitosan （CTS） ,home- made Chitosan pyruvate（P- CTS）, Sulthydryl Chitosan （CTS- SH） as adsorption reagents, we studied their different static and dynamic adsorption to the same metal ion and the competitive adsorption to the mixed metal ions. We analyzed the influence of pH,temperature.adsorption time to the adsorption capacity. We also investigated the influence of flowing speed to the static adsorption and desorption and the recovery of adsorption reagent by means of elution or activation. It＇s the basic research of CTS - X that eliminate the metal ions in the contaminated water.
