摘要
利用氧化还原滴定法测定工业硫化锌的含量,分析了影响硫化锌含量测定的因素,样品测定实验结果表明,该法样本合并标准偏差s_q=0.137％,标准回收率为98.99％～100.20％。
The determination of industrial zinc sulphide content by redox titration method was introduced. The influencing factors of the ZnS content determination was analyzed. The result of the sample determination shows that the combined standard deviation of this method was 0.137% and the recovery was 98.99% - 100.20% .
