Perovskites BaTiO₃, La_0.1Ba_0.9TiO₃ and BaFeO₃ were prepared by different methods and utilized as photo-catalytic material for the degradation of the AO7 dye, with visible light. The toxicity of the treated solutions and the toxicity of perovskite powders that remained in suspension after centrifuged was assessed.
