摘要
采用液液萃取-气相色谱/质谱联用法测定饮用水源水中19种苯胺类化合物,选择DB-5MS色谱柱,讨论了pH值对回收率的影响。方法在0.500 mg/L~5.00 mg/L范围内线性良好1,9种苯胺类化合物的检出限为0.016μg/L~0.067μg/L,标准溶液平行测定的RSD为1.2%~13.2%,实际样品加标回收率为59.3%~85.3%。
A method for determination of 19 aniline and selected derivatives in drink source water was established by GC/MS using DB -5MS column with liquid-liquid extraction. The experimental research found pH influence on the recovery. The results indicated that good linearity was obtained in range from 0. 500 mg/L to 5.00 mg/L, detection limits of 19 kinds of aniline and selected derivatives from 0. 016μg/L to 0. 067μg/L, RSD of standard solution from 1.2% to 13.2% , spiked recovery of samples from 59.3% to 85.3%.
