| Abstract: |
| A GC-MS method was established for the determination of tetrabromobisphenol A(TBBPA) in coatings.The pretreatment conditions and the parameters of GC-MS were optimized.The sample was extracted with dichloromethane-acetone(1∶1) mixed solvent,and purified with silica gel solid phase extraction cartridge,then quantitatively concentrated with parallel evaporation instrument.Under the optimal conditions,the standard curve was linear over TBBPA concentration range of 1-50 mg/L with correlation coefficient more than 0999.The recoveries were in the range of 83.2%-104% with relative standard deviations(n=8) of 2.6%-4.7%.The limit of quantitation(LOQ) was 2 mg/kg.This method was rapid,simple and accurate,and was suitable for the qualitative confirmation and quantitative analysis of TBBPA in coatings. |
