In this study, an analysis was conducted for the determination of tefuryltrione in drinking water using liquid chromatography/tandem mass spectrometry (LC/MS/MS) .
The calibration curve of tefuryltrione, obtained from the results of the study, demonstrated good linearity in the range of 0.2-0.02µg/L. Repeatability of repeated measurements of tefuryltrione standard solution (0.02µg/L, n＝5) was observed to be below 1.2％. In addition, the repeatability (1.8％) , intermediate precision (3.5％) , and accuracy (104％) values obtained via recovery tests for tefuryltrione in drinking water (0.02µg/L, n＝5, 5days) satisfied the criteria provided in the guideline for validation of testing methods for drinking water notified by the Ministry of Health,Labour and Welfare, Japan.
