O potencial do processo de fotocatálise heterogênea consorciado à adsorção para o tratamento de água com Microcystis aeruginosa e seus metabólitos

Abstract

The heterogeneous photocatalysis and adsorption processes are considered economically favorable alternatives for removal of contaminants in water, and they are part of one of the most intensely investigated areas due to the promising character of their applications. However, as the difficult of the heterogeneous photocatalysis technological application is the retention and reuse of the photocatalyst titanium dioxide (TiO2 ), it is still necessary to study techniques for its immobilization in solid supports. This article aims to present the potential of the heterogeneous photocatalysis and adsorption process in a consortium for the treatment of water containing Microcystis aeruginosa and its metabolites. The use of clay minerals is very promising in the areas of adsorption and catalysis for environmental sanitation. In addition, clay minerals are abundant in nature, resulting in low cost in their use and encouraging new research aimed at their use in water treatment.
