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.

“…Direct Orange 26 (DO-26) is an azo dye with high ecotoxicity to aquatic organisms, and its degradation was initiated by photocatalytic degradation under direct sunlight. By using the photocatalyst dose [CoFe 2 O 4 :TiO 2 ] = 50%:50%, a DO-26 degradation efficiency of 65.59% degradation being achieved after 11 h of irradiation [14].…”
