The process was of pseudo-first-order kinetics. The best conditions of decolourization for this dye was the following: initial dye concentration is 50 mg/L, photocatalytic system CoFe2O4: TiO2 (50%:50%) = 0.025 g/100 mL and the initial pH of an aqueous solution of dye is 8.enCoFe2O4Direct OrangePhotocatalysisTiO2conference poster10.21698/simi.2020.ab07
