建立了顶空气相色谱质谱(GC-MS)测定聚氧乙烯化表面活性剂中1，4-二恶烷的方法。采用1，4-d8-二氧六环的同位素稀释法对1，4-二氧六环进行定量，方法的检出限为0.3ppm 1，4-二恶烷。82%的化妆品含有0.3-96ppm的1，4-二恶烷，85%的洗碗品含有1.8-65ppm的1，4-二恶烷。
A headspace, gas chromatography-mass spectrometric (GC-MS) method for the identification and quantitation of 1,4-dioxane in polyethoxylated surfactants is described. An isotope dilution method employing 1,4-d8-dioxane has been used for the quantitation of 1,4-dioxane which is based on the determination of the molecular ion (mass 88) by MS. The detection limit of the method was 0.3 ppm 1,4-dioxane. 82% of the cosmetic products investigated were found to contain 0.3-96 ppm 1,4-dioxane, and 85% of the products for dish washing investigated contained 1.8-65 ppm 1,4-dioxane.
