Comparative Efficiency of the Systems O3/High pH And 03/catalyst for the Oxidation of Chlorobenzenes in Water

Abstract The objective of this study was to investigate the use of advanced oxidation processes to oxidize an industrial wastewater in which chlorobenzenes were found in the range of 1 mg/L to 5 mg/L and a solution of chlorobenzenes whose concentration was 0.03 mg/L, which was prepared from stock solutions. Ozone in a neutral medium (pH=7) was compared with ozone in presence of metallic ions, such as Fe (II), Fe(III) and Mn(II) at concentration of 610-5 M.
