离子选择性电极法测定乙烯利的含量

Determination of ethephon by chlorine Ion selective electrode

拟定了以氯离子选择电极为指示电极,饱和甘汞电极为参比电极,AgNO3标准溶液为滴定剂的电位滴定法测定乙烯利含量的分析方法.该方法简便、准确,标准偏差为0.07,相对标准偏差为0.46%.

This article told us a new potentiomtery that used the chlorine ion selective electrode as the indicating electrode, saturated mercury chloride electrode as the reference electrode and AgNO3 standard solution as the titration reagent to determine the ethephon. The method was simple and accurate. Standard deviation 0.07, relative standard deviation 0.46%.
