摘要
文章对ＥＤＴＡ溶液络合滴定法测定硫酸根进行实用性评论和分析，着重讨论滴定氯化钡、钙镁离子总量和硫酸根返滴定时ＥＤＴＡ的三个用量的关系，并且叙述这些用量所表示的实际意义。以便在盐检测中灵活。
The determination of the sulfate raeical by EDTA solution complexometric titration is Practically reviewed and analysed in the paper. The relation between the total level of barium Chloride, Calcium magnesium ions of titration,and the three use levels of EDTA when sulfate radical is back titrated, is discussed. And the practical meaings of these use levels are described. so the three factors can be used flexibly nad effectively in the inspecton and determination of salt.
