摘要
提出了应用气相色谱法同时测定染发剂中苯酚、邻苯二胺、间苯二胺、对苯二胺、邻苯二酚、间苯二酚、对苯二酚、间氨基苯酚、对氨基苯酚、2,6-二氨基吡啶、2-甲基雷琐辛、5-氨基-2-甲基苯酚、3,4-二氨基甲苯等13染料含量的方法。染发剂样品经乙酸乙酯超声萃取15min,经AgilentHP-5(30m×0.32mm,0.25μm)毛细管柱分离,用氢火焰离子化检测器检测。13种染料的质量浓度均在10～500mg.L-1范围内呈线性,方法的检出限(3S/N)均小于1mg.L-1。在50,100,200mg.L-1等3个添加水平下,13种染料的回收率在85.4%～103.5%之间,测定值的相对标准偏差(n=6)在1.2%～5.2%之间。
A method of CA2 for simultaneous determination of 13 dyes, including phenol, o-phenylenediamine, m-phenylenediamine, p-phenylenediamine, o dihydroxybenzene, m-dihydroxybenzene, p-dihydroxybenzene, m-aminophenol, p-aminophenol, 2, 6-diamino-pyridine, 2-methylresorcinol, 5-amino-2-methylphenol and 3, 4- diamino-methylbenzene in hair colorants was proposed. The 13 dyes in sample were ultrasonically extracted with ethyl acetate, separated on HP-5 capillary chromatographic column （30m×0.32mm,0.25μm） and detected by flame ionization detector （FID）. Linearity ranges for the 13 dyes were found in the same range of 10- 500 mg·L-1, with detection limits （3S/N） less than 1mg·L-1. Tests for recovery were carried out at three concentration levels of 50, 100 and 200mg·L-1, giving values of recovery in the range from 85.4% to 103.5% and RSD＇s （n= 6） in the range from 1.2% to 5.2%.
