%X 建立了基于GC-MS对织物洗涤剂除汗味效果评价方法。样品中汗味特征物质异戊酸经衍生试剂衍生，乙酸乙酯作为内标物，采用气相色谱质谱联用仪对异戊酸含量进行测定。结果表明，样品中异戊酸在浓度范围5~200 μg内线性良好，相关系数可达0.99970，线性方程为：y = 0.122x + 0.055。对空白样品进行3个浓度水平的加标回收实验，回收率在91.2%~109.1%，相对偏差(n = 6)在3.38%~3.97%，当称样量为1 g，检出限可达0.0001%，定量限可达0.0003%。实验采用建立的方法对10个典型样品进行检测，有4款的汗味去除效果相当于或低于标准洗涤剂的去除效果，有6款优于标准洗涤剂的汗味去除效果。结果表明，该方法适用于对织物洗涤剂除汗味效果评价。
A method based on GC-MS was developed to evaluate the deodorization effect of fabric detergents. Isopentric acid, the characteristic substance of sweat taste in the sample, was derivatized by derivatization reagent, and ethyl acetate was used as an internal standard. The content of isopentric acid was determined by gas chromatography-mass spectrometry. The results showed that the linearity of isovalerate in the range of 5~200 μg was good, and the correlation coefficient was 0.99970. The linear equation was y = 0.122 x + 0.055. The recovery rate of the blank samples was 91.2%~109.1%, and the relative deviation (N = 6) was 3.38%~3.97%. When the sample size was 1 g, the detection limit was 0.0001% and the quantitative limit was 0.0003%. The established method was used to detect 10 typical samples, 4 of which were equal to or lower than the standard detergent, 6 of which were better than the standard detergent. The results show that the method is suitable for evaluating the deodorization effect of fabric detergents.
