中文摘要:
      采用聚醚砜滤膜过滤净化水样,以Dionex Pac AG11色谱柱作为分析柱,用液相色谱-串联质谱法测定生活饮用水中2,6-二硝基酚、地乐酚和消螨酚等3种硝基酚类化合物。结果表明,方法在1.00μg/L~200μg/L范围内线性良好,方法检出限为0.09μg/L~0.19μg/L,定量下限为0.36μg/L~0.76μg/L。3种目标物4个质量浓度水平的加标回收率为93.6%~118%,7次测定结果的RSD为0.7%~4.8%。
英文摘要:
      Water samples were purified by polyethersulfone filter membrane. Dionex Pac AG11 chromatographic column was used as the analytical column. Liquid chromatography tandem mass spectrometry (LC-MS/MS) was applied in determining 2,6-dinitrophenol, dinoseb and dinex in drinking water. The results showed that the linearity of the method was good in the range of 1.00μg/L to 200μg/L, the detection limits were from 0.09μg/L to 0.19μg/L, and the lower limits of quantification were from 0.36μg/L to 0.76μg/L. The recoveries of the three target compounds at four mass concentration levels were from 93.6% to 118%, and the RSDs of seven measurements were from 0.7% to 4.8%.
