摘要
研究了用自动电位滴定测定硫氰酸根和氯离子的条件及方法。结果表明:选用银电极为指示电极,217型双液接电极为参比电极,在硝酸介质中既能连续滴定也能分步滴定这两种离子。应用于黑镍镀液分析,方法简便快捷,分析的准确度和精密度完全能满足生产需要。
The conditions and methods for automatic potential titration of thiocyanate and chloride ions were investigated.The results show that by selecting silver electrode as indication electrode,model 217 Double-liquid connecting electrode as reference electrode,the titration can be continuously operated in nitric acid medium,and these two kinds of ions can also be titrated by steps.When used in analyzing black nickel plating bath,it is easy and fast to operate,and the accuracy and precision can completely meet the demands of production.
