摘　　要： 对用自制的不溶性交联淀粉黄原酸酯(DX-4)脱除废水中的Zn2+进行了试验,结果表明,在pH为6~10范围,只需5min,Zn2+脱除率可达90%以上,处理后的废水符合国家工业废水排放标准;在酸性或碱性介质中残渣稳定。 Experimentation of eliminating Zn^2＋ in waste water was perpetrated by self-made infusibility interleaving starch xanthate （DX-4）. Results indicated that the elimination ratio of Zn^2＋ was upwards 90% at the conditions of pH 6-10 and reaction time of 5 minutes. The treated waste water can accorded with the National Discharge Standard of industry waste water. Residue was stabilization in the solution of acidity or alkaline.
