Rapid Characterization of Polyvinyl Chloride and Phthalate Plasticizers by Fourier Transform-Infrared Spectrometry

A method of rapid characterization of polyvinyl chlorid (PVC) and phthalate plasticizers by Fourier transform infrared spectrometry (FT-IRS) was proposed.Detection of PVC was performed by the attenuated total reflection (ATR) technique using germanium as crystal material.Detection of phthalate plasticizers was carried out by the transmission method.Separation and purification of the sample were done by the dissolution and precipitation method using tetrahydrofuran as solvent and absolute alcohol as precipitant.By the method deseribed effective separation of the polymer from the plasticizers was achieved.
