摘 要: 采用气相色谱~质谱联用测定了妇婴洗涤用品及化妆品中二恶烷的含龟。结果表明,在5.0~100.0μg/g范围,色谱峰面积与质量浓度之间呈良好的线性关系,线性相关系数(r)为0.9986,回收率为84.0%~99.6%,该法具有简单、准确快捷等特点,可以在妇婴洗涤及化妆品检测中推广使用。 The determination of dioxane in woman and infant detergent and cosmetic by gas chromatography - mass spectrometry was developed. The results show that in the range of 5.0 - 100. 0 黎彧g/g, there are all good linear relationships between the concentration and the relative peak areas, the corrlation coefficient(r) was 0.998 6, the recoveries were 84.0% -99.6%, this method is simple, easy to control, fast and suitable for use in woman and infant detergent and cosmetic industry.
