工业污水中黄原酸酯含量的测定

Determination of xanthic ester in industrial wastewater

浮选矿捕集剂黄原酸酯极少量地排入水中也能使水的味道极其难闻。为了处理该污水,需要测定出其含量。作者利用黄原酸酯与镍盐的络合物在有机溶剂中显色的特性。探讨出光度法或比色滴定法测定其含量的快速途径。该方法操作简便,易于掌握与推广。

Xanthic ester is a kind of catcher in the floatation of minerals. Though only a very little amount of xanthic ester is discharged into water, it smells wondrously bad. In order to treat this kind of wastewater, its content needs to be determined. Since the complex of xanthic ester and nickelate is characterized by color-displaying in organic solvent,a fast way to determine its content by spectrophotometry or colorimetric titration has been discussed. This method is easy to be operated, mastered and popularized.
