ETUDE CINETIQUE DE LA PHOTODEGRADATION DU COLORANT RED 6 EN SOLUTION AQUEUSE.
Journal Title: International Journal of Advanced Research (IJAR) - Year 2019, Vol 7, Issue 9
Abstract
The dyes are widely consumed as an input in artisan dyeing in Ivory Coast. Their detection in surface water and in groundwater is evidence of the lack of training in the good practice of textile dyeing and the environmental pollution that results from it. The dye \"Red 6\" widely used in dye compositions, was selected for this study. With the aim of eliminating them in synthetic waste simulating wastewater from dyeing plants, direct photolysis and photocatalysis were carried out respectively in a cylindrical reactor placed on a magnetic stirrer and 12 cm below an axial cap containing the irradiation lamp. The experiments were carried out with a polychromatic (λ≥285 nm) and monochromatic (λ = 254nm) lamp. The results indicate that the molecule is difficult to degrade with degradation rates of 24.49% and 38.77% respectively for the lamps used. The use of titanium dioxide (TiO2) as a catalyst allowed a better degradation of the \"Red 6\" dye under the polychromatic lamp compared to direct photolysis with a degradation rate of 98.18% after 300 min of irradiation
