| Abstract: | Ozonation, adsorption onto activated carbon and catalytic ozonation in batch and in a fixed-bed reactor for the removal/degradation of phenol and COD were investigated. In the case of batch ozonation the oxidation capacity was greater than 6.9 g of phenol/g O3, while the continuous ozonation system degraded 40% of the phenol and reduced the COD by 27.9%. The adsorption process provided over 99% removal for phenol and COD; however, it treated only 5 L compared with 17 L for the combined process, which also increased the total area and pore volume of the activated carbon, due to the formation of pores and a widening of micropores. |
