| A method was developed for the simultaneous determination of 7 residual benzene series（BTEX）,including benzene,toluene,ethylbenzene,p-xylene,m-xylene,o-xylene and styrene，in resin crafts by headspace gas chromatography（HG-GC）.The extraction conditions,including solvent type,extraction temperature and time,were investigated,and the chromatographic conditions for HS-GC,including headspace bases,equilibrium temperature and time,sample granularity,were optimized.The results showed that 7 residual benzene series were preferably separated and good quantitative analyses were achieved under the headspace equilibrium temperature at 130 ℃ for 60 min,where the diameter of sample particle was smaller than 2mm and the DB-WAX capillary operation was chosen.Under the optimal conditions，the calibration curves were linear in the range of 0.1-500 μg with correlation coeficients higher than 0.999．The limits of quantitation（LOQs,S/N=10） of this method were between 0.1 μg?g-1 and 0.4 μg?g-1.The recoveries at three spiked levels ranged from 93% to 114% with relative standard deviations（RSDs） of 0.7%-4.8%.The established method was rapid and accurate,and was suitable for the analysis of benzene series in resin crafts. |
