| Abstract: | In our previous study, we first prepared TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) aiming at breakthrough to enhance the dispersibility of TiO2 nanoparticles in PVC matrix to maximize catalytic activities of TiO2 nanoparticles. The present study is aimed o measure and compare the amount of dioxin emitted from both TEPVC and PVC incineration, estimating the dioxin inhibition efficiency of TEPVC. TEPVC and PVC were first combusted in a well-controlled, small-scale incinerator at 700 C. Synthetic air (21% oxygen) was introduced as the air for combustion. The combustion gas was trapped using a thimble filter, water and diethylene glycol impingers in a cold-bath, and amberlite XAD-2 resin absorption tubes, sequentially along the stream. The thus-treated samples were extracted, spiked with internal standards, and purified through a multi-layer silica-gel column and alumina column. Finally, the samples were condensed and used for dioxin analysis based on HRGC/HRMS. The TEPVC shows reduced dioxin emission due to the enhanced dispersibility of TiO2 nanoparticles by nanoparticle encapsulation |
