摘　　要：在HNO3介质中,偏酸性条件下,加入一定量的C3H6O溶液,利用电位滴定测定铜电解液中的水溶氯,试验发现,此方法加大了电位的突变值,使得滴定终点显著。通过相应的对比实验和加标回收试验的验证,此方法的相对标准偏差7.37%,回收率为98.4%～101.7%,结果准确、方法可靠。In nitric acid medium, under acidic conditions, a certain amount of acetone was added, potentiometric titration using a water-soluble copper chloride electrolyte, testing found that this method is to increase the value of the potential mutation, such that the titration end point is remarkable. Through a series of comparative experiments spiked recovery test results show that this method is the relative standard deviation is 7.37%, recoveries between 98.4% - 101.7%. Accurate and reliable method, is recommended.
