| Abstract: | Volatile organic compounds were determined by purge and trap-GC/MS,then the conditions of purge and trap treatment and secondary mass were optimized.The correlation coefficients of the calibration curve equations were above 0.999 1.The detection limit of method for VOCs was 0.1～0.4 μg/L and the recoveries was 84.9%～101% with precision of 1.6%～6.9%(n=7).The method provides the advantages of simple operation,accuracy,high efficiency,and is suitable for the determination of VOCs in batch of groundwater samples. |
