Abstract
By using advanced oxidation processes assisted by solar radiation in CPC (Compound Parabolic Concentrator) reactors it was possible the decolourisation (98%) of the azo dyes acid red 151 (AR151), acid orange 7 (AO7) and acid blue 113 (AB113). The dose of Fenton reagent was determined through a central composite design and by using response surface methodologies. The experimental strategy allowed the reduction of the reagent dose up to 40%, providing even the same decolourisation percentages as well as the generation of potentially biodegradable effluent.
Key words: Azo, optimization, photo-Fenton, response surface, solar collector
