摘要
采用DowexPraktCl-和DowexPraktH+阴阳离子交换混合柱 ,甲醇为流动相 ,运用示差折光仪将未磺化物检出并记录。其相对平均误差和精密度分别为 4.0 %和 0 .6 %。该法适用于测定脂肪醇硫酸盐 ,脂肪醇醚硫酸盐 ,烷基苯磺酸等中的未磺化物。
The unsulfated matter was determined with a set of ion-exchange columns, a differential refractometer and a suitable mobile phase. The relative average deviation and precision were 4.0% and 0.6% respectively. This method was feasible for determination of the unsulfated matter in fatty alcohol sulfates, fatty alcohol ether sulfates and alkylbenzenesulfonic acids.
