Synthesis, characterization and study of activity of a floating photocatalyst for water treatment.
Advanced oxidation processes (AOPs) permit the total degradation (mineralisation) in aqueous solutions of toxic organic molecules for human being and for environment.
In this work, we are interested in the synthesis of novel photocatalysts based on composites TiO2/PANI and TiO2/AS and supported on floating substrates (cork).These catalysts show the unique feature of floating on the water surface where optimum illumination and oxygenation occurs leading to the formation of a higher rate of radicals (OH·) and therefore a strong increase in their photocatalytic efficiency.
This study concerns the application of this advanced oxidation processes (AOPs) to treatment of wastewater contaminated with methylene blue dye selected as a model pollutant in a solar photo-reactor containing one of the floating catalysts. The results obtained enabled as to show that photocatalytic degradation of this dye allows abatement superior 80% during 4 hours of treatment according the first apparent kinetic order.
The floating photocatalysts can be applied directly in the contaminated wastewater reservoirs located in remote places without any special equipment or installation and using the sun as a sole source of energy.
