Direct Orange via TIO2 assisted photocatalysis

In this paper, photocatalytic degradation of direct orange dye solution was achieved in the presence of CoFe2O4 : TiO2 as catalyst under solar light. 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.
