| 摘 要： | 应用自动电位滴定法,在pH=5的总离子强度缓冲溶液存在的微酸性水溶液中,用0.05 mo1·L-1硝酸银标准溶液作为滴定剂,测定了湿法脱硫废水中氯化物含量。实验对不同浓度氯化物的脱硫废水样品分别进行了实验并加以分析。用标准加入法进行了回收率试验,结果在95.21%～107.46%之间。用不同样品进行了精密度试验,方法的相对标准偏差（n=6）在0.19%～5.30%之间。

| Abstract: | By automatic potentiometric titration,at pH=5 sourish water mixtures with total ionic strength buffer,wet de-sulfurization wastewater was determinted with titration teagen of 0.05 mo1·L-1 AgNO 3.The different concentration of chloride desulfurization wastewater samples were experienced and analyzed.Tests for recovery were made by the stan-dard addition method,and the recovery were between 95.21% and 107.46%.Tests for precision were made with different samples,and the relative standard deviation（sRSDs）were between 0.19% and 5.30%. |
