Characterization on Dioxin Emission of TiO2 Nanoparticle-Encapsulating Poly(vinyl chloride) (TEPVC) compared to conventional PVC
TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) was combusted in a well-controlled laboratoryscale incinerator at a temperature of 700 °C, and then dioxins (PCDDs, PCDFs and coplanar-PCBs) formed in the exhaust gases were analyzed by high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). TEPVC sample was prepared by the suspension polymerization of vinyl chloride monomer (VCM) with the 1.0wt% of surface modified amorphous TiO2 nanoparticles based on the VCM weight reported in our previous study [1]. TEPVC shows valuable dioxin inhibition property due to the enhanced dispersibility of TiO2 nanoparticles by encapsulation. Dioxin emission from TEPVC combustion was suppressed at the efficiencies of 39~82% by 0.926 wt% of encapsulated amorphous TiO2 in TEPVC compared to conventional PVC.
