摘　　要：采用气相色谱/质谱联用测定环境水体中壬基酚、壬基酚一氧乙基醚、壬基酚二氧乙基醚、4-叔辛基酚、4-叔辛基酚一氧乙基醚和4-叔辛基酚二氧乙基醚,用二氯甲烷对水样液液萃取,浓缩后添加BSTFA+TMCS(体积比为99∶1)在室温下衍生化0.5 h。方法在0.001 mg/L～5.00 mg/L范围内线性良好,目标化合物的检出限范围为4.0×10-7mg/L～8.8×10-7mg/L,空白加标样品平行测定的RSD为5.1%～8.8%,回收率为85.6%～110%。A method for determination of nonylphenol,nonylphenol monoethoxylate,nonylphenol diethoxylate,4-tert-octylphenol,4-tert-octylphenol monoethoxylate and 4-tert-octylphenol diethoxylate in water by gas chromatography coupled with mass spectrometry-selected ion monitoring has been established.Dichloromethane is suitable for APEOs and APs by liquid-liquid extraction.N,O-Bis(trimethylsilyl) trifluoroacetamide and trimethylchlorosilane(V/V,99 ∶ 1) was used as the derivation reagent for APEOs and APs,and the time of derivation which was 30 minutes at room temperature.Good linearity was obtained in the range from 0.001 mg/L to 5.00 mg/L.The detection limits ranged from 4.0 × 10-7 mg/L to 8.8 × 10-7 mg/L.Recoveries ranged from 85.6% to 110% and RSD from 5.1% to 8.8%.
