| titleOfInvention | A method for the detection of trace estrogen, nonylphenol and bisphenol A in complex environmental matrices |
| abstract | The invention discloses a method for detecting trace amounts of estrogen, nonylphenol and bisphenol A in a complex environmental matrix. In the method, the complex environmental matrix to be measured is sludge, and the complex environmental matrix to be measured is sequentially subjected to ultrasonic extraction, Liquid-liquid distribution purification, two-step solid phase extraction purification and sample preparation treatment to obtain the sample to be tested; wherein, in the ultrasonic extraction, an internal standard for isotope purification is added, and methanol is used as the extraction solvent; the obtained sample to be tested is subjected to high-efficiency liquid The trace amount of estrogen, nonylphenol and bisphenol A in the sample to be tested is detected by phase chromatography in series with triple quadrupole mass spectrometry, and the concentrations of the estrogen, nonylphenol and bisphenol A are obtained. The method can quickly and accurately determine the concentrations of estrogen, nonylphenol and bisphenol A in the sludge of complex environmental matrix. The method is simple to operate, resistant to matrix interference, good in reproducibility and high in reliability. |
