Abstract

A new method was developed for the determination of benzene substances by headspace liquid-phase micro extraction-gas chromatography.The sample was agitated in 30 ℃ water for 25 min,octanol was extraction solvent.The FID detector,temperature-programmed method and split injection were chosen.The linearly dependent coefficient was 0.983 3～0.993 4 and spiking average recovery was 95.88%～97.70%.The results show that the method is reliable and sensitive on the real samples.
