| Abstract: | An analytical method was developed for the determination of volatile organic compounds(VOCs) in soil and sediment samples by GC/MS with purge & trap system.Experimental parameters,including preservation methods,purge time and temperature were optimized.The method had been successfully applied to determine VOCs in some soil and sediment samples.The relative standard deviation was less than 5.0%.And the recovery was ranged from 78.2% to 99.8% for soil samples,55.2%~95.2% for sediment samples. |
