BACKGROUND A new method based on accelerated solvent extraction was developed for the extraction and determination of 11 organophosphorus flame retardants by using a high‐performance liquid chromatography–tandem mass spectrometry technique. RESULTS After optimization of the extraction temperature (80 °C), the extraction solvent ( n ‐hexane), the flush volume (40%) and the static extraction time (4 min), all 11 organophosphorus flame retardants illustrated good linearities ( R > 0.999). The limits of detection of the method ranged from 0.016 to 26.58 µg kg −1 in the different matrices. The recoveries were 90.4–111.2% with relative standard deviations 0.21–5.3% for the various aquatic products. CONCLUSION The proposed method was applied successfully to detect 11 organophosphorus flame retardants in aquatic products, including grass carp, ribbon fish, mud fish, common eel, shrimp and frog. © 2018 Society of Chemical Industry
