The invention discloses a method for simultaneously measuring residues of 12 kinds of OPEs (Organophosphate Esters) in a water sample and sediment, belongs to the technical field of measurement of organophosphorus esters, and discloses a method for detecting residues of 12 kinds of phosphate ester compounds in a water body and sediment by using a high-performance liquid chromatography-mass spectrometry technology in combination with solid-phase extraction and liquid-liquid extraction. The method comprises the following steps: enriching a water sample with an HLB (Hydrophile-Lipophile Balance) solid-phase extraction column; extracting sediment with an ultrasonic solvent; analyzing by a high-performance liquid chromatography-mass spectrometer MRM (Multiple Reaction Monitoring) monitoring ion mode; quantifying by an external standard method. Specific to most OPEs, the method has the advantages of low detection limit, high stability and high detection sensitivity; when the method is used for rapidly screening the
