Nonylphenols are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail. Nonylphenols can come in numerous structures, all of which may be considered alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics. Nonylphenol has attracted attention due to its prevalence in the environment and its potential role as an endocrine disruptor and xenoestrogen, due to its ability to act with estrogen-like activity. The estrogenicity and biodegradation heavily depends on the branching of the nonyl sidechain. Nonylphenol has been found to act as an agonist of the GPER (GPR30).

The invention discloses a method for detecting estrogen, nonyl phenol, octyl phenol and bisphenol A in water body sediment based on an accelerated solvent extraction (ASE), liquid-liquid extraction (LLE) and liquid chromatography / tandem mass spectrum (LC / MS / MS) technology. The method comprises the following steps of: performing accelerated solvent extraction by using acetone as an extracting agent to extract the estrogen, the nonyl phenol, the octyl phenol and the bisphenol A in the water body sediment; dissolving residues generated after extract is blown by nitrogen by using 1mol / L sodium hydroxide solution, performing centrifugal collection on the supernate, and performing liquid-liquid extraction by using ethyl acetate under the condition that the pH is equal to 2; and performing concentration detection by using a 3200QTRAP type liquid chromatography / tandem mass spectrometer and an Agilent 1100 high performance liquid chromatography system of American Applied Biosystem Company and an automatic sample injector of American Agilent Company. The recovery rate is 59 to 94 percent, and the detection limit is 0.04ng / g.
