| titleOfInvention | Method for simultaneously detecting multiple estrogens in sludge |
| abstract | The invention provides a method for simultaneously detecting multiple estrogens in sludge, wherein the method is used for simultaneously detecting multiple estrogens in sludge by using accelerated solvent extraction-solid phase extraction-supper high efficiency liquid phase-tandem mass spectrometry. The method concretely comprises the following steps of: extracting estrogens from a sludge sample by accelerated solvent extraction after pre-treatment of the acquired sludge sample, enriching and purifying an extract by a solid phase extraction column, eluting the estrogens in an HLB column by an acetonitrile solution containing 5% of ammoniacal liquor, detecting the various estrogens in the sample by combining an internal standard method through supper high performance liquid chromatography-tandem mass spectrometry. Detection limits on five kinds of estrogens by the method is lower than 0.8ng/g, and the method has advantages of high recovery rate, high sensitivity, good repeatability, simple operation and solvent saving, and satisfies simultaneous detection of a plurality of and a trace amount of estrogens in the sludge. |
