| Abstract: | The contents of benzene,toluene and xylene in artificial boards were determined by microwave-assisted solid phase headspace-gas chromatography.The effects of microwave power on peak areas of the three compounds with increasing irradiation time were discussed.The detection limits of the three compounds were 3.6,9.1 and 13.4 ng · g-1 respectively.Recoveries for the three compounds were in the range of 86.9%—109.4%.The microwave-assisted solid phase headspace-gas chromatography is a simple,rapid method,and suitable for the direct determination of benzene,toluene and xylene in artificial boards,without any pretreatment. |
