KINEMATIC EVALUATION OF WET OXIDATION FOR PHENOLIC CONTAMINATED WATERS

Wet oxidations catalyzed by MnO2, Co2O3, and CuSO4.5H(2)O, were carrie d out for waters containing 1000 mg/L phenol and 1500 mg/L p-chlorophe nol, respectively. CuSO4 . 5H(2)O was demonstrated to be the most effe ctive in reducing the concentration of phenols in waters. Rate constan t and activation energy of the oxidation were also obtained, the enhan cement of catalysts on the oxidation rate of phenol was found to be in increasing order of MnO2, Co2O3, and CuSO4 . 5H(2)O. The cocurrent an alyses of total organic carbon and high pressure liquid chromatography illustrated that the end products after oxidations, being intermediat es within 10% extent in the liquid phase.
