Research Of P-chlorophenol By Ozone With M/ACF Catalysts And It's Kinetic Decomposition

Eflects of catalyst, pH value, system temperature, initial solute concentration.the remove rate of P-cholorophenol with increasing pH of solution, increasingtemperature and enhancing gas flow rate, but the degree of enhancing descended with high temperature. The remove rate of P-chlorophenol decreased with increasing concentration of P-chlorophenol .The P-chlorophenol decay followed a pseudo first-order reaction.The M/ACF catalyzed ozonation for degrading P-chlorophenol in water was investigated.experiment results shows P-chlorophenol was removed 70% in 2 minutes by O₃+Fe/ACF and O3+Co/ACF, and P-chlorophenol was removed 70% in 6 minutes by O₃ alone. The results indicated Fe/ACF was found to be the most effective approach among these M/ACF catalysts to remove P-chlorophenol solution.The possible function mechanism of M/ACF catalytic ozonation is dexomposition of ozone to produce hydroxyl radical and enhancement of oxidation ability of ozone by forming electrophilic center.A rough economy estimation of the catalytic ozonation process was carried out. The EE/O(Electrical energy per order) value and the stoichiometric coefficient of process were 2.07 kW.h/Order/m³ and the EE/O value of 03 alone were 3.55 kW.h/Order/m³, result shows catalytic ozonation process is more economical than ozonation process...
