Blue Dye Degradation In An Aqueous Medium By A Combined Photocatalytic Andbacterial Biodegradation Process, Gabriela Perez Osorio, Flor Del Rocio Hernandez Gomez, Janette Arriola Morales, Maribel Castillo Morales, Jose Carlos Mendoza Hernandez

Turkish Journal of Chemistry

This paper aimed at implementing a treatment system for polluted water with textile dyes, starting with a photocatalytic decomposition process using sunlight as a source of energy and continuing with a bacterial biodegradation process, in order to reach degradation percentages higher than those obtained using only one of the processes mentioned above. When water treatment with the dye in the combined system was over, an acute ecotoxicity test was performed to make sure that toxic metabolites were not produced due to biodegradation. Solophenyl Blue azoic dye, and Erionyl Blue and Terasil Blue anthraquinone dye-colored solutions were treated with the Pd/Al$_{80}$ …
