【摘要】 本文以壳聚糖为主要原料，分别经过悬浮交联和复合制备得到壳聚糖（Ｃｈｉｔｏｓａｎ）树脂吸附剂（简称ＣＳ吸附剂）和壳聚糖—活性炭（Ｃｈｉｔｏｓａｎ－Ａｃｔｉｖｅｃａｒｂｏｎ）复合吸附剂（简称ＣＳ—ＡＣ吸附剂）。研究影响制备吸附剂的诸因素；测定两种吸附剂的性能；探讨两种吸附剂对印染废水的脱色和对有毒金属离子的去除。研究结果表明：本研究条件下制得的ＣＳ和ＣＳ—ＡＣ吸附剂比表面积分别为８２．９Ｍ２／ｇ和９３７．３Ｍ２／ｇ；对亚甲基蓝溶液（５００ｍｇ／Ｌ）的静态吸附量为１４１．２ｍｇ／ｇ吸附剂和８３５．１ｍｇ／ｇ吸附剂；ＣＳ吸附剂对印染废水的动态脱色量为１２６．９ｍｇ／ｇ吸附剂；两种吸附剂对有毒重金属Ｐｂ（２＋）的去除率均达９０％以上，而且耐酸、碱性能较好，均为优良的颗粒状吸附剂。更多还原

【Abstract】 Chitosan resin adsorbent and chitosan-active charcoal composite adsorbent have been prepared through suspension polymerization and composition respectively. The influence of factors on preparation and the properties of both adsorbents were also studied. Both adsorbents have been used to decolorize and remove toxic metal ion from waste water in printing and dyeing process. Results show that specific surface areas of two adsorbents prepared in this condition are 82. 9m2/g and 937. 3 m2/g respectively; static adsorption capacities of methylene blue from solution (500mg/L) are 141.2mg/g and 835. 1mg/g for printing and dyeing waste water both decolorizing effciency of waste water and removing efficiency of toxic metal ion are over 90%. Moreover, acid proof and base proof properties of both adsorbents ate better.更多还原
