Determination Of Restricted Bromated And Phosphorous Flame Retardants In Textiles By Gas Chromatography-Mass Spectrometry

Extracted and determination of 5 Restricted retardants in Textiles was established in this paper.An analytical method for the Determination of Restricted Bromated (PBB) :2-Bromobiphenyl;2,5-Dibromobiphenyl;4,4'-Dibromobiphenyl;2,4,6-Tribromobiphenyl and phosphorous Flame Retardants (TOCP) in Textiles was established by Gas Chromatography-Mass Spectrometry. The linear ranges of 5 flame retardants were 5～1000ng, and the detection were0.46~0.80ng. The total time of the method was0.83min. Restricted retardants in Textiles were extracted with acetone- hexcane by ultrasonic instrument. The effect of various parameters, selection of extraction solvent, time of extraction and extraction time were investigated. The efficiency of ultrasonic extraction was compared with of Soxhlet. The results indicated that the optimal analytical conditions was that ultrasonic extraction acetone- hexcane(V/V=1/4,40mL)and 40min at twice.The microwave assisted extraction(MAE)was used for the extraction of PBBs in textile sample. The influence factors of extraction temperature, time, solvent on the extraction efficiency of MAE were discussed. The results indicated that the optimal analytical conditions was that extraction temperature, solvent and time was selected as 60°C, acetone- hexcane(V/V=2/1,40mL)and 5min respectively.The method recoveries were in the range of 96.0%～114.7%.
