A simple and selective method was developed for determination of the concentration of 2,4-xylenol in river and sea water samples using gas chromatography/mass spectrometry (GC/MS). Trace amounts of 2,4-xylenol were collected in a Oasis HLB Plus cartridge, eluted with acetonitrile. The method detection limit of 2,4-xylenol was 1.4 ng/L. The trace peaks of 2,4-xylenol were found in water samples from the river and the sea, and the concentrations were all less than 1.4 ng/L. The nine peaks of the 2,3-, 2,4-, 2,5-, 2,6-, 3,4-, 3,5-xylenol, and o-, m-, p-ethyl phenol that gave the same m/z ratio were separated efficiently.
开发了一种简单且具有选择性的方法，用于使用气相色谱/质谱联用仪（GC/MS）测定河流和海水样品中2,4-二甲酚的浓度。痕量的2,4-二甲酚被收集在Oasis HLB Plus固相萃取柱中，用乙腈洗脱。2,4-二甲酚的方法检测限为1.4 ng/L。在河流和海水的水样中发现了2,4-二甲酚的痕量峰，其浓度均低于1.4 ng/L。2,3-、2,4-、2,5-、2,6-、3,4-、3,5-二甲酚以及邻、间、对乙基苯酚的九个具有相同m/z比的峰被有效分离。
