文摘
Nonylphenol (NP) is a degradation product of nonylphenolpolyethoxylate surfactants and has been reported tooccur in water and sediments from urban areas. TechnicalNP is composed of several structural isomers, andconventional gas chromatography-mass spectrometrytechniques have tentatively identified up to 22 components.Isolation and characterization of individual isomers in atechnical NP mixture is important, because of the differencesin estrogenic and bioaccumulation potential among theisomers. In this study, comprehensive two-dimensional gaschromatography (GC × GC) combined with massspectrometry (MS) enabled tentative identification of 102components of NP from a technical mixture. GC ×GC-MS was also used to quantify two NP isomers inriver water samples. This is the first study to use GC ×GC-MS to characterize NP isomers in technical mixturesand for quantitative analysis of NP in river waters.
