Abstract:
A comprehensive analytical method based on ultra performance liquid chromatography tandem mass spectrometry has been developed for the simultaneous determination of 16 carcinogenic and allergenous dye stuffs (acid red 26, basic red 9, disperse blue 1, acid violet 49, disperse blue 3, solvent yellow 1, dispersed blue 106, disperse orange 3, disperse yellow 3, basic violet 1, basic violet 3, disperse red 1, solvent yellow 3, disperse blue 124, solvent yellow 2 and disperse orange 37).Various toy samples, including textile, leath er, paper, wood, balloon, modeling clay, limitation tattoo and aqueous liquid, were extracted under ultrason ication.Qualitative and quantitative analysis was carried out for the analyte under the MRM mode after the chromatographic separation on Waters ACQUITY UPLC BEH C_(18)(50 mm x 2.1 mm, 1.7 μm) column.The limits of quantitation(LOQ) for the 16 dyestuffs were in the range of 1.0-8.0 μg/kg.The mean recoveries at the three spiked levels of 5-100 μg/kg were 81.3%-98.6%, with the intra-day precision less than 11% and the inter-day precision less than 14%.The method is accurate, rapid, sensitive, and adapt to the inspec tion of the 16 dyestuffs in toys.
