| Abstract: | 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. |
