Adsorption Processes Coupled with Photochemical Depolution of Waters Contaminated with Direct Orange-26 Azo Dye

Abstract

Abstract The present work aims to study the adsorption processes and the photochemical depollution of the waters contaminated with Direct Orange textile dyes - 26 released into the water. Also, the paper shows the polysulfone (PSf) membranes, used for adsorption processes of the textile dyes azo - direct-orange-26, presenting the kinetics and experimental adsorption conditions for such processes. Advanced oxidation processes (AOP) processes used in photochemical depollution technologies are studied for water contaminated with Direct Orange 26 textile dye, after a preliminary adsorption process, with ZnFe2O4 ferrite photocatalysts.
