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%。
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, 2,4-dinitrobenzene 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.
