1. detect a method for 21 kinds of hydroxyl PBDEs (OH-PBDEs) in soil simultaneously,It is characterized in that, comprise the steps:

  • (1) with organic solvent extraction pedotheque to be measured, described organic solvent is selected from normal hexane, secondNitrile, methanol, dichloromethane, methyl tertiary butyl ether(MTBE) and NaOH-ethanol;

    (2) extracting solution obtaining step (1) carries out thickening-purification technology;

    (3) by the product Ultra Performance Liquid Chromatography of step (2)-triple quadrupole rods tandem mass spectrometry instrument inspectionSurvey, and compared with the hydroxyl PBDE standard substance of operation repetitive, it is thus achieved that quantitative result.
