“…Due to the existence of less free iron ions, less HO • are generated in the media; besides, the oxidation potential of this radical diminishes when the pH is increased [6,49]. Thus, Fenton reactions for the degradation of several compounds are considerably reduced at low and high pH values as well.…”

Abstract:The basic and applied aspects of Fenton and Fenton-like processes for removal of pollutants using zerovalent iron materials, including nanoparticles, are reviewed in this article. Only those examples including the use of the iron materials together with hydrogen peroxide addition are included. The mechanistic aspects of homogeneous and heterogeneous Fenton processes, still under discussion, are displayed. The use of biogenic generated iron nanoparticles for removal of pollutants is discussed due to their novelty and economy of synthesis.

“…During the oxidation of organic contaminants, the ultimate goal is to produce simple, relatively harmless inorganic molecules [40]. Advanced oxidation processes are characterized by their production of the hydroxyl radical (ÁOH), a very strong oxidant, in sufficiently high concentrations to affect water quality.…”

Antibiotics are nonbiodegradable, can survive at aquatic environments for long periods and they have a big potential bio-accumulation in the environment. They are extensively metabolized by humans, animals and plants. After metabolization, antibiotics or their metabolites are excreted into the aquatic environment. Removal of these compounds from the aquatic environment is feasible by different processes. But antibiotics are not treated in conventional wastewater treatment plants efficiently. During the last years studies with advanced oxidation processes (AOPs) for removal of these pharmaceuticals from waters has shown that they can be useful for removing them fully. Advanced oxidation processes (AOPs) can work as alternatives or complementary method in traditional wastewater treatment, and highly reactive free radicals, especially hydroxyl radicals (OH) generated via chemical (O 3 /H 2 O 2 ,O 3 /OH -), photochemical (UV/O 3 ,O 3 /H 2 O 2 ) reactions, serve as the main oxidant. This study presents an overview of the literature on antibiotics and their removal from water by advanced oxidation processes. It includes almost all types of antibiotics which are consumed by human and veterinary processes. It was found that most of the investigated advanced oxidation treatment processes for the oxidation of antibiotics in water are direct and indirect photolysis with the combinations of H 2 O 2 ,TiO 2 , ozone and Fenton's reagent.

“…Na fotólise direta, a degradação do substrato ocorre quando o mesmo se encontra em seu estado excitado, gerado a partir da absorção de radiação UV em comprimentos de onda apropriados, iniciando assim a ruptura das ligações químicas das moléculas (PARSONS, 2005;DOMÈNECH et al, 2001).…”
