Abstract
The current study investigates the utilization of fly ash (FA), foundry sand (FS) and clay in composite form for the degradation and decolourization of methyl orange. In this study, both the photo-Fenton and photocatalysis process are incorporated into a single unit to evaluate the dual effect. The best results for the degradation (66%) and decolourization (89%) of methyl orange in fixed mode were obtained with FS/FA/Clay beads coated with TiO2. The composite beads proved its durability by showing only 4% (degradation) and 3% (decolourization) decrease in catalyst efficiency after 50 times of recyclability. To confirm, the morphology and presence of TiO2 and iron in the composite beads SEM/EDS and XRD analysis were done.
