Abstract

The experiments to oxidize the refractory chemicals, 1,2- Dichloroethane, 1,1,1-Trichlotoethane and 1,1,2,2- Tetrachloroethane using Ozone, Hydrogen Peroxide and Ultraviolet Radiation have been conducted in a ss-304 photoreactor. The reaction kinetic models have been proposed and through the experiments we demonstrate that these models for these compounds perfectly. Analysis is done by gas chromatograph for the substrate concentration and the gas/liquid mass transfer coefficients are calculated. The reaction late constants are determined by use of the Rosenbrock Hillclimb Optimization Algorithm in conjunction with the Fourth-Order Runge- Kutta method on a digital computer. By comparing the effects of O₃,O₃/UV and H₂O₂/UV in these three compounds, we conclude that the H₂O₂/UV process is the best way to degrade these toxic-chemicals in water.
