In this study, Coomassie brilliant blue (CBB), green (BG), and rhodamine (Rh) dyes were used to simulate dye-rich wastewater. Adsorption degradation of these (2 μM, 10 30 μM) on diatomite (DE) evaluated under light (L) dark (D) conditions. The adsorption dye-DE composites followed pseudo-second-order kinetics at all concentrations conditions had R 2 > 0.99, thus showing a good fit. calculated equilibrium amount q e,(cal) was coherent with the value experimental e,(exp). poorest photocatalysis occurred prompting functionalization TiO2 Fe3O4 nanoparticles (NP(s)). highest dye efficiencies (DGeff) for μM 86.79% (CBB-DE-Fe3O4, 72 h), 96.10% (BG-DE-TiO2, 52 81.74% (Rh-DE-TiO2, 48 Rh-DE-TiO2 fastest degradation.
