Determination of 7 Plasticizers in PVC plastics by Gas Chromatography-Mass Spectrometry

A simple,rapid and accurate method for the determination of plasticizers in polyvinyl chloride (PVC) plastics was established in this paper. Seven plasticizers of phthalates in PVC plastics were efficiently extracted in chloroform by means of ultrasonic-assisted extraction,then determined by GC-MS. Recoveries of the method were in the range of 93.08%-104.1%. Values of detection limit (S/N=3) were ranged in 0.05-10.0 mg·L-1 and values of RSD′s (n=5) in the range of 0.5%-5.4%.
