摘　　要：建立自动顶空-毛细管气相色谱同时测定水中8种苯系物的方法。采用stabilwax-DA色谱柱,对平衡温度、平衡时间等顶空条件进行了优化,并对水中苯系物进行测定。8种苯系物平均加标回收率为93.3%～115.0%,检出限为1.2～2.0μg/L,测定结果的相对标准偏差为1.8%～7.3%(n=6)。该法操作简单、灵敏度高、重现性好,可以满足饮用水中苯系物的测定。Determination of benzene series in drinking water by headspace gas chromatography was established. The experimental conditions of headspace, such as the balance temperature and balance time were optimized. Benzene series in drinking water were determined by headspace gas chromatography. The recoveries of benzene series were 93.3%-115.0%. The relative standard deviation of detection results was 1.8%-7.3%(n=6), and the detection limit was 1.2-2.0 μg/L. The method is simple, sensitive and reproducible. It is s...
