Environmental Simulataneous Determination of 20 Phthalate Acid Esters Migration in PVC Products by Gas Chromatography-Mass Spectrometry
The Phthalate Acid Esters migration situation was affected on contact time and temperature with the distilled water and 4% aqueous acetic acid as an environmental simulation.A simple and rapid method for the simultaneous determination of 20 phthalate acid esters mingration from PVC products to Environmental Simulataneous by GC-MS was developed.The results show that migration would increase with contact temperature and time growth.When 40℃C and 2 hours, migration reached its maximum.The correlation coefficients(R) of 20 PAEs were over 0.999, and detection limits 0.02 mg/L.The average recoveries of 20 PAlEs were ranged from 96.7% to 100.5%.In addition, the relative standard deviations(RSDs) were ranged 1.60%~ 5.10%.The method has advantage of simplicity, sensitivity and repeatability, can simultaneous determination of 20 PAEs form PVC products to environmental media.
