Resumen:

The Fenton process, based on the Fenton reaction discovered in 1894, is used to treat a large variety of water pollutants. Iron and hydrogen peroxide are used to generate hydroxyl radicals that react with the pollutants, oxidizing them into carbon dioxide and water. One of the drawbacks of the typical homogeneous Fenton process is the presence of large quantities of dissolved iron in the effluent aft er treatment. The resulting ferric hydroxide sludge requires further separation and disposal, which makes the process relatively expensive. In order to overcome this problem, recent research has focused on the development of iron oxide catalysts, like the heterogeneous photo-Fenton process under UV-Vis irradiation. In this chapter, we will describe the preparation and characterization of nanostructured iron oxide materials and their use for the treatment of wastewater containing critical and emerging pollutants, such as metalaxyl (a phenylamide pesticide), using this photo-assisted process. © 2014 by Scrivener Publishing LLC.
