摘  要:
The residue of five benzene series in drinking water were determined by headspace-gas chromatography to oplimize the measure conditions.The results showed that the optimum condition was showed as follows:NaCl adding amount at 2.0g,equilibrium temperature at 50℃,equilibrium time at 30min,sampling pressure at 137.900kPa,and radio of vapor to liquid at 18∶4.
