Abstract:

A HPLC-ESI-MS/MS method was developed for the qualitative and quantitative of nine kinids of phthalates multiresidues in food packaging materials HPLC-ESI-MS/MS. Samples were extracted using acetonitrile. The analytes were separated using 0.1% fomic acid-methanol system as the mobile phase with a linear gradient elution program , and determined by a tandem mass detector. The mean recovery for each analyted ranged from 65.28% to 98.33%, with the relative standard deviations from 5.35% to 11.22%, and the limits of detection were about 5-20 ng/ml.

Key words: phthalates, food packaging materials, HPLC-ESI-MS/MS, multi-residues
