摘　　要：采用电位滴定法同时测定食盐中Cl-、I-含量,此方法反应灵敏,操作简单,专一性强,符合测定结果和分析的技术要求,讨论了由E-V曲线、△E/△V-V曲线、△2E/△2V-V曲线确定电位滴定终点的方法。The potentiometric titration was used to determine Cl-and I-content in the salt simultaneously,this method＇s response was sensitive,the operation was simple,and the method was specific strongly,it conformed to the determination result and the analysis specification,the method to determine the end-point of potentiometric titration by the E-V curve,the △E/△V-V curve,the △2E/△2V-V curve was discussed.
