摘要
用氯离子选择电极以多次标准添加作图法测定了硝酸钴平的微量氯离子.方法简单,快速,测定的标准偏差小于0.001%,加料回收率为96%~103%,最低可测定0.001%的氯离子.
The determination of micro amount of chloride in cobalt nitrate with achloride-selective electrode by means of the consecutive standard addition method has beendeveloped. The procedure is simple and rapid, with standard deviations less than 0.001%and the recoveries between 96% to 103%. Chloride. content as low as 0. 001 % can bedetermined.
