摘要:
建立了在线富集固相萃取-超高效液相色谱串联质谱法测定水中对硝基苯酚的方法。经过滤的水样用在线固相萃取系统富集后,以氨水-甲醇系统作为流动相进行梯度洗脱,通过超高效液相色谱串联质谱仪进行检测。方法的检出限为3.52 ng/L,回收率为91.6%~108%,相对标准偏差为5.5%~9.5%。该方法可大大简化复杂的前处理过程,提高灵敏度及准确性,可用于大批量地表水中对硝基苯酚的测定。

Abstract:
A method for the analysis of p Nitrophenol in water was developed using online solid phase extraction(online SPE) coupled with ultra performance liquid chromatography tandem mass spectrometry(UPLC MS/MS).Filtered water samples were enriched by on line solid phase extraction system,gradient eluted by aqueous ammonia methanol,and then detected by tandem mass spectrometry.The detection limit, the recoveries and the relative standard deviations of the method were 3.52 ng /L,91.6%~108% and 5.5%~9.5%, respectively.The method can greatly simplify the complex pretreatment process,improve the sensitivity and the accuracy, and is suitable for the analysis of p Nitrophenol in large quantities of surface water.
