CATALISADORES BASEADOS EM ÓXIDOS DE FERRO SUPORTADOS EM CARVÃO ATIVADO DESTINADOS À REAÇÃO DE FENTON PARA DEGRADAÇÃO DE POLUENTES ORGÂNICOS: UMA REVISÃO BIBLIOGRÁFICA

Pollution of river and groundwater by waste from the textile and dye industry brings innumerable short-term and long-term environmental damage. Advanced oxidative processes (AOPs) are shown as effective alternatives in the treatment of effluents, degrading organic pollutants present in the environment. Fenton's reaction is an AOP that presents itself as a very promising option. In the present work a bibliographical revision was done on Fenton reaction, using iron oxide as catalyst. The advantages of using a solid matrix to support the catalyst, such as activated carbon, have also been addressed, since it is a very porous material with a high specific surface area, which increases the amount of active sites. This support can be synthesized from several sources, such as green coconut shell, peanut shell, coffee bean, wood, lignin, bamboo, chitosan, coal, sugar cane bagasse and corn cob.
