摘要
用二阶导数紫外分光光度法直接测定混合物中烷基酚聚氧乙烯醚和烷基苯磺酸钠的含量。此法不需经任何分离手续,快速、简便、准确,标准偏差±0.01,回收率在98％以上。
This Paper deals with the determination of alkylphenolpolyoxyethylene ether and sodium alkylbenzenesulfonate in mixture by second derivative UV-spectrophotometric method. It is not necessery to separate the sample in the analytical process. This method is simple, convenient, fast and accuracy. Under the given experimental condition, the mean recoveries of alkyphenol-polyoxyethy-lene ether and sodium alkylbenzensulfonate are over 98%. The standard deviation is ±0.01.
