摘　　要：对二次盐水中碘离子的测定方法进行了深一步的研究,详细地介绍了利用阴极溶出伏安和标准加入法测定二次盐水中的碘离子测定,并首次提出了利用在检测样品溶液中通高纯氮气消除了溶解氧对阴极溶出氧化还原电位的影响,并对标准加入法和标准曲线法在阴极溶出伏安法测定二次盐水中碘离子进行了比较。This paper makes a further study on the testing method of iodide ion in the sec-ondary brine and introduces using cathode stripping voltammetry and standard addition method to test the iodide ion. And this paper first proposes the concept of removal of influence of dissolved ox-ygen on cathode stripping oxidation reduction potential through high purity nitrogen gas in the test sample solution. Meanwhile, it compares with the standard addition method and the standard curve method when using cathode stripping vohammetry to test the iodide ion in the secondary brine.
