| Abstract |
Brominated flame retardants(BFRs) have been widely used as additive or reactive chemical in polymers and textiles. An analytical methods for polybrominated diphenyl ethers (PBDEs) in textile samples using gas chromatography/mass spectrometry (GC/MS) and thermal desorption (TD)-GC/MS were described. Decabromodiphenyl ether (deca-BDE) in textiles was extracted using ultrasonification method with n-hexane/ methylene chloride (1:1, v/v) for GC/MS analysis. For purification, the absorbent of silica was applied to retain the impurities. Analysis of deca-BDE with TD-GC/MS, which is not required for extraction and clean up. In the monitoring of deca-BDE in textiles, TDGC/MS using the pyrolysis system which can be confirmed in the presence of deca-BDE in textiles is effective. This method have the advantage of rapid, simplicity, economy and small amount of sample, while conventional GC/MS method is needed a lot of time and high amount of solvent. However, the determination of low concentration of deca-BDE in textiles by GC/MS analysis is appropriate. |
