Photo-fenton remediation of wastewaters containing agrochemicals
The photochemical degradation of agrochemicals in aqueous solution by means of advanced oxidation processes (AOPs) was studied. The photo-Fenton process was evaluated in terms of the time evolution of dissolved organic carbon (COD) and chemical oxygen demand (DOC), their total removals, and increase...

| description | The photochemical degradation of agrochemicals in aqueous solution by means of advanced oxidation processes (AOPs) was studied. The photo-Fenton process was evaluated in terms of the time evolution of dissolved organic carbon (COD) and chemical oxygen demand (DOC), their total removals, and increase in biodegradability of treated wastewater. Under the experimental conditions studied, the process showed to be superior to other AOPs, at any Fe(II) and H2O2 concentrations. The results pointed towards the use of solar irradiation and low cost commercial application.<br>Neste trabalho, estuda-se a degradação fotoquímica de defensivos agrícolas presentes em efluentes aquosos, por meio de processos oxidativos avançados (POAs). Tais processos são baseados na ação do radical hidroxila (HO•), oxidante poderoso e não seletivo. Em particular, o processo foto-Fenton é avaliado quanto à redução da demanda química de oxigênio (DQO) e do teor de carbono orgânico dissolvido (COD), e ao aumento de biodegradabilidade dos efluentes. Os resultados abrem perspectivas para emprego de irradiação solar e aplicação em escala comercial a baixo custo. |
