Abstract
The content of characteristic pollutants including methyl tert-butyl ether (MTBE) and benzene, toluene, ethyl benzene, p-xylene, m-xylene and o-xylene (BTEX) were determined by head-space-GC. A HP-FFAP capillary column was used in this method. In the mass concentration range of 14.8μg·L-1~1760μg·L-1, there were good linearity relationships between the GC peak areas and the mass concentrations of components with correlation coefficient above 0.999.The detection limits were in the rage of 2.0μg·L-1~2.3μg·L-1. Tests for recoveries and precision were made by standard addition method, values of recoveries and RSDs (n=6) found were in the range of 95%~105% and 0.8%~5.5%.
