摘　　要：采用不同的二硫化碳和环氧氯丙烷的加入量来进行淀粉原酸酯的合成,并利用双因素无重复试验方差分析方法对环氧氯丙烷和二硫化碳的用量与重金属铬捕集能力的关系进行了显著性试验,试验确定了制备具有最佳捕集重金属铬能力的淀粉黄原酸酯的环氧氯丙烷加入量的范围,以及相应硫含量。A series of starch - xanthate were prepared with different addition of CS2 and epichlorohydrin. The trapping chromium capacity of starch - xanthate with different CS2 and epichlorohydrin dosage was investigated by the method of two - factors analysis of variance without repeated trial. It indicates the relationship between the trapping chromium capacity and the different dosage of CS2 and epichlorohydrin. The optimal usage of epichlorohydrin is 20 -40g and the corresponding sulfur dosage is 0. 5% -0. 7%.
