摘　　要：采用带硫化银膜的银电极和长寿命银复合电极测定冶炼厂含氯水质中氯离子含量时,会得到不同的测量结果。针对这两种电极的测量条件和影响因素进行探讨,并对水质中氯离子进行测定。结果表明:两种电极的相对误差均小于±3%,相对标准偏差均小于2%,但带硫化银膜的膜电极测试结果整体高于长寿命银复合电极,带硫化银膜的膜电极精密度优于长寿命银复合电极。Different measurement results can be obtained when using silver electrodes with silver sulfide film and long-life silver composite electrodes to determine the chloride ion content in chloride containing water in smelters.Explore the measurement conditions and influencing factors of these two electrodes,and determine chloride ions in water quality.The results showed that the relative error of both electrodes was less than±3%,and the relative standard deviation was less than 2%.However,the test results of the membrane electrode with silver sulfide film were overall higher than those of the long-life silver composite electrode,and the precision of the membrane electrode with silver sulfide film was better than that of the long-life silver composite electrode.
