摘要
用顶空法测定饮用水中5种苯系物残留量,对测量条件进行了优化,结果表明:最佳的测量条件为NaCl加入2.0g,平衡温度为50℃,平衡时间为30min,进样压力为137.900kPa,气液比为18∶4。
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.
