Abstract
A simple,rapid and accurate gas-chromatographic method for the determination of benzene,toluene and xylene was studied.The analysis was made by using HP-5 capillary column and FID detector.We could be gotten the contents of benzene,toluene and xylene by only one injection.All components and internal standard were separated in 185 mins.The results with good linearities(r=0999 3,0999 8 and 0999 2)were obtained.The coefficients of variation were 078%,060% and 068%.The recoveries of the method were 981%-1011%,979%-995% and 980%-1002%.
