摘　　要：消毒剂过硫酸氢钾复合盐颗粒中氯化钠为氯离子的供体,其含量至关重要。为了测定过硫酸氢钾复合盐颗粒中的氯化钠含量,探索了电位滴定法测定氯化钠含量的方法。结果显示:电位滴定法在氯化钠含量为10~200 mg范围内呈良好的线性关系(回归方程为y=0.1717x+0.0229,R^2=0.9995),精密度较好(RSD=0.39%),准确度高(回收率99.43%~100.34%,RSD=0.33%),耐用性好。3批样品氯化钠含量的测定结果均符合含量限度的要求(组内RSD小于1.50%)。说明电位滴定法可用于消毒剂过硫酸氢钾复合盐颗粒中氯化钠含量的测定。The sodium chloride in the disinfectant potassium hydrogen persulfate composite salt particles is a donor of chloride ions,and its content is very important.In order to determine the sodium chloride content in the potassium hydrogen persulfate composite salt particles,the potentiometric titration method was used in the experiment.The results showed that the method had a good linear relationship within the range of sodium chloride content of 10 mg-200 mg(the regression equation is y=0.1717x+0.0229,R^2=0.9995),a good precision(RSD=0.39%),high accuracy(recovery rate of 99.43%-100.34%,RSD=0.33%)and a good durability.The sodium chloride content determination results of the three batches of samples met the content limit requirements(The internal RSD in group is less than 1.50%).It is concluded that the potentiometric titration method can be used to determine the sodium chloride content in the new potassium hydrogen persulfate composite salt particles.
