摘　　要：本文分别采用离子色谱和化学法对水溶性染料产品中氯化物进行测定。离子色谱法利用峰面积外标法对结果进行定量计算,并对样品的前处理过程进行分析,实验表明:对水溶性染料进行加热更利于产品中氯化物的释放,该法操作方便,重复性好。并对该化学法进行优化,提高结果准确性,确定了测定下限。In this paper,ion chromatography and chemical methods were used to determine the chloride in water-soluble dye products.The peak area external standard method was used to quantitatively calculate the results,and the sample pretreatment process in ion chromatography was analyzed.The experiments showed that heating the water-soluble dyes was more conducive to the release of chloride in the products.The ion chromatography method has convenient operation and excellent repeatability.The chemical method was optimized to improve the accuracy of the measurement results and the lower limit of measurement was determined.
