| Resumo: | In the last decades, various chemical oxidation techniques have been developed to overcome the inconveniences associated to conventional treatment of industrial wastewaters. Advanced oxidation processes (AOPs) have been reported to be effective for the degradation of soluble organic contaminants from wastewaters containing non-biodegradable organic pollutants, because they can often provide an almost total degradation, under reasonably mild conditions of temperature and pressure. Among them, Fenton process is widely implemented, although it has many drawbacks such as pH sensitivity, formation of sludge and loss of active species. Therefore, this work is specially focused on different alternatives to overcome the above drawbacks using Fenton-like processes for homogeneous and heterogeneous oxidation of phenol. Thus, the addition of chelating agents allowed broading the pH range of efficient operation. In turn, the use of nano zero valent iron supported on carbon materials enhances the removal performance and eliminates the subsequent separation of iron hydroxide sludge. |
