摘　　要：建立了一种测定羟乙基磺酸钠质量分数的分析方法,即试样通过与强酸性阳离子交换树脂进行离子交换,然后以溴甲酚绿为指示剂,用氢氧化钠标准滴定溶液滴定分析羟乙基磺酸钠的质量分数。并讨论了相关因素对测定的影响,方法简便、准确、快速、重复性好,取得了满意的结果。A method was built for determining the content of sodium hydroxyethyl sulphonate. Sodium hydroxyethyl sulphonate in the sample is determined by ion-exchange with Strongly acidic cation exchange resin and titration with methanolic sodium hydroxide,with bromocresol green indicator. And the effect of correlative factors was discussed. It is a practical method,which operation is simple and convenient and can get exact result quickly.
