一种快速测定羟乙基磺酸钠质量分数的方法

A Rapid Method for Determining the Content of Sodium HydroXyethyl Sulfonate

建立了一种快速离子交换法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动态离子交换,钠离子被交换成氢离子,然后以氢氧化钠标准滴定溶液滴定交换出来的氢离子,分析出羟乙基磺酸钠的质量分数,并讨论了树脂量和交换时间对测定的影响,该方法快速简便、准确、重复性好,取得了满意的结果。

A method was built for determining the content of sodium hydroxyethyl sulphonate by ion-exchange.Dynamic exchange between sample and resin,and sodium ions are exchanged for hydrogen ions,then determination of sodium hydroxyethyl sulphonate can be obtainted through titrating hydrogen ions by sodium hydroxide,and the effect of resin quantity and exchange time was discussed.The method is rapid,simple,accurate,reproducible,and satisfactory results have been achieved.
