摘要
文章研究了在pH5．5～6．0之间，用EDTA标准溶液滴定锌合金中的锌镉总量，再用数学公式分别计算出锌量和镉量。试验表明该方法操作简便快速，结果准确，相对标准偏差小于0．8％。
This article discussed the titration of the total content of Zinc and Cadmium in Zinc alloy by EDTA standard solution in the pH range of 5.5 - 6.0, and the respective calculations for Zinc and Cadmium with mathematic formulae. The method is simple and rapid, and shows accuracy and good precision. The relative standard deviation （RSD） is less than 0.8%.
