【摘要】采用SPE-GC/MS法测定水中对硝基氯苯和2,4-二硝基氯苯,优化了试验条件。对硝基氯苯在1.00 mg/L~80.0 mg/L之间线性关系良好,2,4-二硝基氯苯在1.00 mg/L~50.0 mg/L之间线性关系良好,方法检出限对硝基氯苯为0.6μg/L,2,4-二硝基氯苯为2.1μg/L,回收率对硝基氯苯为86.2%~94.7%,2,4-二硝基氯苯为87.3%~95.4%。更多还原

【Abstract】 The trace p-nitrochlorobenzene and 2,4-dinitrochlorobenzene in water were determinated by SPE-GC/MS after experimental condition optimized.The linear range is from 1.00 mg/L to 80.0 mg/L in p-nitrobenzene,2,4dinitrobenzene from 1.00 mg/L to 50.0 mg/L.The linear relations are good.The limit of determination for p-nitrobenzene and 2,4-dinitrobenzene are 0.6 μg/L and 2.1 μg/L respectively.The recovery ranges are 86.2%～94.7% for p-nitrochlorobenzene and 87.3%～95.4% for 2,4-dinitrobenzene.更多还原
