An analytical method for determination of restricted bromated (PBB) , such as 2-bromo-biphenyl, 2, 5-di bromobiphenyl, 4,4'-dibromobiphenyl, 2,4,6-tribromobiphenyl and phosphorous flame retardants(TOCP) in textiles was established by gas chromatography. The samples were extracted by ultrasonic extraction and the optimum conditions of extraction were obtained as the following : the volume ratio of acetone to n-hexane was 2 to 8, the extraction time was 40 min and the solvent volume was 40 mL. The linear ranges of 5 kinds of flame retardants were 5-1000 ng, and the detection were 0.46-0.80 ng. The method recoveries were in the range of 96.0% -114.7%, and the method precisions were 4.63%-6.78%. The total time of the method was 0.83 min.
