摘　　要：建立了采用顶空气相色谱质谱联用法测定洗护用品中二恶烷含量的方法。标准工作溶液与样品溶液采用相同的平衡条件,计算结果更加简便准确。对一些样品进行测定,平均加标回收率为95%～106%,相对标准偏差小于5%,最低检出限为0.5μg/mL,对洗护用品中二恶烷的测定具有很好的应用价值。A method for determination of dioxane in toiletries using headspace gas chromatography mass spectrometry is established. The standard and sample solution are tested with the same equilibrium conditions, the test results are more simple and accurate. After validation by sample spiked , the recovery of these samples was between 95 % -106 %, and the RSD was less than 5%, the detection limit was 0.5 ug/mL, which had good application value on testing dioxane in toiletries.
