A Kinetic Model of the Hydrogen Peroxide/UV Process for the Treatment of Hazardous Waste Chemicals

摘要

The effectiveness of the H_2O_2/UV process has been investigated using trichloroethylene (TCE), tetra- chloroethylene (PCE), benzene, and toluene as model compounds. The UV source used in this study was the low pressure mercury vapor lamp using mainly 254 nm of radiation. For irradiation of aro- matic compounds such as benzene and toluene at high concentration, by-products formed by the ir- radiation process were found to reduce the oxidation rate; these by-products also acted as UV ab- sorbers in competition with the parent compounds.
