摘　　要：建立了顶空气相色谱法快速测定烷基糖苷中正辛醇、正癸醇的方法,优化了顶空进样的参数和色谱分析的条件。结果表明:残留醇在0.05~1.00 mg/L范围内与色谱峰面积线性关系良好,相关系数R^(2)>0.999以上,重复性RSD<0.5%,精密度RSD<2.0%。烷基糖苷样品中的正辛醇和正癸醇加标回收率分别为100.2%~103.2%和98.9%~101.4%。该方法简便、快速、准确,适用于工厂大规模测定烷基糖苷中的残留脂肪醇。A method for rapid determination of octanol and decanol in alkyl glycosides by headspace-gas chro⁃matography is established.The parameters of headspace injection and chromatographic conditions are opti⁃mized.The results show that the residual alcohol has a good linear relationship with the chromatographic peak area in the range of 0.05-1.00 mg/L,the correlation coefficient R^(2)>0.999,the repeatability RSD<0.5%,and the precision RSD<2.0%.The recoveries of octanol and decanol in the alkyl glycoside samples are 100.2%-103.2%and 98.9%-101.4%,respectively.The method is simple,rapid and accurate,and is suitable for the large-scale determination of residual fatty alcohols in alkyl glycosides in factories.
