摘　　要：采用电导法，用氯化钡标准溶液滴定水样中硫酸根的含量，对测定结果的影响因素进行了探讨。本方法测定的回收率在９８～１０２％之间，装置简单，试样测定时间仅需几分钟，准确度较高，适用范围广，如海水、卤水、自来水、深井水、雨水和部分工业废水等硫酸根含量的测定。In this paper the content of sulfate radical was determined by conductance method using standard solution titration of barium chloride.The influence factors to the determination result were discussed.The rate of recovery by this method was about 98% 102%.The method which has high accuracy is rapid,simple and widely used example for the measurements of sulfate radical in sea water,bittern water,running water,rain water,deep well water,some industrial waste waterand etc.
