Advanced oxidation processes used in food dyes removal

Abstract

AOP(s) – Advanced oxidation processes, are a set of chemical treatment methods and procedures used to remove organic and inorganic pollutants present in wastewater by oxidation through the reaction who involve hydroxyl radicals (OH-) formation. Oxidative processes usually refer to a subset of chemical processes which employ hydrogen peroxide (H2O2), UV light and ozone (O3). In order to total mineralization of synthetic dyes from food industries, the art proposes the use of catalytic oxidation processes.
