我们应用了一种基于固相萃取 (SPE) 的方法，通过柱上接口与气相色谱-质谱联用，测定水样中的一组内分泌干扰化合物。我们优化了影响 SPE 工艺和转移步骤的参数，并使用该方法分析河流、沿海和自来水。在全扫描采集模式下，仅预浓缩 15 ml 水样即可测定所有化合物。在一些实际样品中测定了浓度在 0.02 至 0.5 µl(-1) 之间的邻苯二甲酸二正丁酯、邻苯二甲酸苄基丁酯、邻苯二甲酸双(2-乙基己基)酯和己二酸双(2-乙基己基)酯。 (C) 2002 Elsevier Science B.V. 保留所有权利。
We have applied a method based on solid-phase extraction (SPE), on-line coupled to gas chromatography-mass spectrometry through an on-column interface, to determine a group of endocrine-disrupting compounds in water samples. We have optimised the parameters affecting the SPE process and transfer step and used the method to analyse river, coastal and tap waters. In the full-scan acquisition mode, all the compounds were determined by preconcentrating only 15 ml of water sample. Di-n-butyl phthalate, benzylbutyl phthalate, bis(2-ethylhexyl) phthalate and bis(2-ethylhexyl) adipate at concentrations between 0.02 and 0.5 mug l(-1) were determined in some real samples.
