PROCESSOS OXIDATIVOS AVANÇADOS (POAs): UMA REVISÃO DA IMPORTÂNCIA DE FOTOCATÁLISE NA DESCOLORAÇÃO DE CORANTES TÊXTEIS COMO O VERDE MALAQUITA

Abstract

The industrial development and the excessive use of dyes by the textile industry have leveraged in recent years, consequently, have led to increased contamination of natural resources. It is not new that Brazil is among the countries that most use textile dyes, which generates high water contamination, thus causing numerous harm. In order to minimize these impacts, studies have been carried out and are still being carried out aiming at the removal of these contaminants. The use of Advanced Oxidative Processes (AOPs), as well as homogeneous and heterogeneous photocatalysis, has been one of the viable alternatives for this purpose. It was observed that the search for methods of removing dyes has always been studied by different areas of research, so that the waters are free of dye, as well as the need for the correct treatment of this contaminated waste is specified for industries.
