| 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 0.016 μg/L to 0.067 μg/L, RSD of standard solution from 1.2% to 13.2%, spiked recovery of samples from 59.3% to 85.3%. |
