摘　　要：分别用国产高聚物ＧＤＸ１０２、ＧＤＸ５０２小球及它们等质量比例混合的树脂对模拟水样中的痕量有机物进行富集，带电子捕获检测器的毛细管气相色谱法同时分析水中邻、间、对二氯苯，硝基苯，对硝基甲苯，邻、间、对硝基氯苯，２，４－二硝基甲苯，邻苯二甲酸酯（二甲酯、二乙酯、二丁酯）共１２种有机物。上述有机物除二氯苯外，回收率达７０％以上，方法具有很高的灵敏度，适用于饮用水及水源水中痕量有机物的分析。The trace organic compounds of chloro - aromatics, nitro - aromatics and phthalate esters in synthetic water samples were enriched by resin of GDX102, GDX502 and their mixture, respectively. Twelve compounds- p-, o-, m- dichlorobenzene, nitrobenzene, 4-nitrotoluene, p-, o-, m-nitrochloro- benzene, 2, 4-dinitrotoluene, dimethyl-, diethyl-, dibutyl-phthalate-were simultaneously analyzed by capillary gas chromatography with a electron capture detector. The recoveries of the compounds are above 70% except dichlorobenzenes. The method is sensitive and applicable to the analysis of the trace organic compounds in drinking water and source water.
