In this study, an analysis was conducted for the simultaneous determination method of aniline and quinoline in drinking water using liquid chromatography/tandem mass spectrometry.
The calibration curves of aniline and quinoline, obtained from the results of the study, demonstrated good linearity in the range of 1.0 to 20 μg/L of aniline standard and in the range of 0.01 to 0.020 μg/L of quinolone standard. The repeatability of repeated measurements of aniline standard solution (0.02 μg/L, n＝5) was observed to be below 0.82％ and the repeatability of repeated measurements of quinoline standard solution (0.02 μg/L, n＝5) was observed to be below 2.7％. In addition, the repeatability (4.8-5.6％), intermediate precision (4.8-12％), and accuracy (98.8-107％) values obtained via recovery tests for aniline and quinoline in drinking water (aniline: 1.0 μg/L, and quinoline: 0.01 μg/L, n＝5, 5days) satisfied the criteria provided in the guidelines for the validation of testing methods for drinking water notified by the Ministry of Health, Labour and Welfare, Japan.
