| 摘 要： | 采用反相高效液相色谱法测定化妆品中对苯二胺等５种染料中间体，以ＺｏｒｂａｘＣ８为固定相，Ｖ（三乙醇胺）∶Ｖ（水）∶Ｖ（乙腈）＝０．９５∶９４．０５∶５为流动相，加入磷酸调ｐＨ值为７．７，检测波长为２８０ｎｍ。样品用体积分数为９５％的乙醇超声提取，回收率为８７％～１０７％（ｎ＝６），相对标准偏差为２．３％～６．４％。

| Abstract: | A reversed-phase high performance liquid chromatographic method was used to detect 5 dyes including p-phenylenediamine in cosmetrics. A Zorbax C8 column was used and mobile phase was V (triethanolamine):V(water):V(acetonitrile) = 0.95:94.05:5 adjusted to pH 7.7 by phosphoric acid. The wavelength 280 nm was selected. Samples were extracted with 95% ethanol by ultrasonic method. The recoveries were 87%-107% and the relative standard deviations were 2.3%-6.4%. |
