3 Principle of the method

Hexabromocyclododecane in marine organisms is extracted with n-hexane, and then concentrated by rotary evaporation and purified by silica gel solid phase extraction column. Constant volume, separation by high performance liquid chromatography column, elution with methanol, acetonitrile and water as mobile phase, by high performance liquid chromatography-tandem mass spectrometry The contents of α-HBCD, β-HBCD and γ-HBCD were determined by internal standard method.
