摘要:
建立了固相萃取-液相色谱/质谱测定水中硝基苯酚类化合物的方法。在最优条件下,7种硝基苯酚类化合物的分离度较好,目标物在0.02~3.00 mg/L范围内线性良好,相关系数均>0.998,检出限为0.007~0.026 μg/L,加标回收率为71.1%~95.9%,精密度为7.36%~18.6%。该方法操作简便、准确,具有较好的实用性。

Abstract:
A method based on solid phase extraction coupled with liquid chromatography mass spectrometry was established for the determination of nitrophenols in water. Under the optimum experimental conditions, 7 kinds of nitrophenols can be separated completely. The linearity of the regression equations was excellent. The limits of detection were from 0.007 to 0.026 μg/L. The recoveries were in the range of 71.1%~95.9%. The relative standard deviations were between 7.36% and 18.6%. The method is simple, accurate and practical.
