| 中文摘要: |
| 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〖JP20〗∶〖JP〗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4.0×10-7 mg/L～8.8×10-7 mg/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%。 |
| 英文摘要: |
| 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〖JP20〗∶〖JP〗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%. |
