Abstract

The separation of hydroquinone and some of its ether derivatives was studied by micellar electrokinetic chromatography with sodium dodecyl sulphate as an anionic surfactant in the background electrolyte. The optimized method was used for the determination of hydroquinone in a sample of skin-toning cream. On-column detection at 254 nm with caffeine as an internal standard gave good quantitative results.

摘要

以十二烷基硫酸钠作为背景电解质中的阴离子表面活性剂，采用胶束电动色谱法研究了对苯二酚及其一些醚衍生物的分离。将优化后的方法用于测定一款美白面霜样品中的对苯二酚。以咖啡因作为内标，在254 nm处进行柱上检测，得到了良好的定量结果。
