摘　　要：采用三种方法(重量法、EDTA滴定法、离子色谱法)测定脱硫液中硫酸盐的含量,并比较其测定结果。结果表明:三种测定方法各有优缺点,其中EDTA滴定法相对标准偏差小、费用低、操作简单、准确度高,是测定脱硫液中硫酸盐的最佳方法。Three methods（gravimetric method, EDTA titration method and ion chromatography） were used to determine the content of sulfate in desulfurization, and the measurement results were compared. The results indicated that three methods have their advance and weakness. EDTA titration method has minimum relative standard deviation, inexpensive, simple, accurate, which is the best method for the determination of sulfate in desulfurization liquid.
