| Abstract: | The photooxidation in four systems of CFC-11+H2O2,CFC-11+H2O2+O2, CFC-12 +H2O2, and CFC-12+H2O2 +O2 were studied. H2O2 was irradiated by a low pressure mercury lamp and OH radicals were produced. The OH radicals can induce photooxidation of CFCs. The products of photooxidation were determined by a Fourier Transform Infrared Spectroscopy with a 20 m optical path cell.The products were COFCI, CO2 and HCI for CFC-l-11+H2O2 and CFC-11+H2O2+O2 systems.COF2,CO,and HF for CFC-12+H2O2 and CFC-12+H2O2+O2 systems.Based on those results,the mechanism of photooxidation was suggested. |
