摘　　要：本文以环氧氯丙烷与淀粉进行交联反应,然后再进行黄原酸化反应制得不溶性淀粉黄原酸酯(ISX),用ISX对含镉废水进行了处理试验,对其去除效果及影响因素进行了实验研究,并对其去除机理进行了初步探讨。试验结果表明,当其用量为651 mg/L时,Cd2+离子去除率达99.30%。与其它方法相比,该法具有成本低、操作简单、无毒无害、易于分离、去除率高,回收废渣处理不会引起二次污染等优点。The insoluble starch xanthate （ISX） was prepared with the material of starch, 1-ctfloro-epoxypropane, carbon disulfide and metal salt etc,The performance of treatment and the factor influence were studied by treating wastewater containing cadmium. Furthermore, the mechanism of removal of ISX is discussed.It is shown that the removal effciency of Cd^2＋ in wastewater is 99,30% when the dosage of ISX is 651 mg/L, By comparison with other treatment technique, this method exhibits some advantages, such as easy operation, low cost, non-hazards, high removal efficiency and no secondary pollution, etc.
