锡铅焊料中高含量镉的测定-EDTA络合滴定法

摘要

The determination of the high levels of cadium in tin-lead solder with EDTA comprexometric titration method was studied. The determination conditions, the acidity of the solution, the interference of coexisting ions, and the recovery method accuracy and precision visits were comprehensively discussed. This methods maybe used for determination of 10% - 20% (by mass) of cadmium in tin-lead solder.%研究了用EDTA络合滴定测定锡铅焊料中高含量镉的方法。对测定条件、溶液酸度、共存离子干扰情况、加标回收率、方法的准确度和精密度考察进行了较全面的讨论。本法可用于锡铅焊料中10％～20％（质量分数）镉的测定。
