摘　　要：研究了树脂吸附 /气相色谱法同时测定水中 10种硝基苯类污染物的方法。水样流经GDX - 5 0 2树脂富集柱 ,硝基苯类污染物得到吸附富集 ,然后用苯洗脱 ,洗脱液经K -D浓缩器浓缩定容后 ,以带电子捕获检测器的毛细管柱气相色谱测定。讨论了水样的富集条件、污染物的洗脱条件对测定的影响 ,确定了色谱条件 。A method for simultaneous determination of nitrobenzene in water by use of resin enrichment/gas chromatography is studied. First, the water sample flows through columns of GDX 502 porous resin, next the column is eluted with benzene, and after that, the eluate, after concentrated with K-D concentrator, is determined by gas chromatography with electron capture detector. The effect of enrichment and elution conditions on determination is discussed. Chromatographic analysis conditions are determined and the feasibility of the method is proved.
