水中SO2-4含量是水质常规分析中的重要项目之一，也是影响水中离子平衡的重要因素，地下水和地面水一般都或多或少的含有硫酸根，因此硫酸根的检测十分重要。在微酸性溶液中，氯化钡与硫酸根生成硫酸钡沉淀，过量的钡离子在pH＝10条件下，用乙二胺四乙酸二钠溶液滴定，通过计算得出硫酸根含量。对EDTA-Ba容量法测水中硫酸根的条件进行了改进，使得硫酸根的测定更快速。

The SO2-4 in water was one of the important items in the water quality analysis , and was also an important factor affecting the ion balance of water , groundwater and surface water were generally containing sulfate more or less , so testing the content of sulfate was very important.In subacid solution , barium sulfate precipitate was produced by barium chloride and sulfate radical , and excess barium ions can be titrated by disodium ethylenediamine tetraacetate , using the data, the content of sulfate radical can be counted.The determination method condition of sulfate using EDTA -Ba volumetric method was improved and determined the content of sulfate more quickly.
