标准摘要
[中文适用范围]： 通过连续萃取、分离、蒸发、再溶解和通过离子交换树脂过滤，测定氯化钠、阴离子活性物质、聚乙二醇和聚乙二醇硫酸盐的含量。 由阴离子表面活性剂(烷基醚硫酸盐)的含量和通过两相滴定测定的阴离子表面活性物质的含量，估算平均相对分子质量。 [外文原描述]： By successive extraction, separation, evaporation, redissolution, and filtration through an ion-exchange resin the contents of sodium chloride, anionic-active matter, polyglycol, and polyglycol sulfate are determined. From the content of anionic surface active agent (alkylether sulfate) and the anionic surface active matter content determined by two-phase titration, the mean relative molecular mass is estimated.
