About

The invention refers to a process for obtaining in the ultrasound field a catalytic system with the structure of metal oxides used in the advanced treatment of waste water resulting from the pharmaceutical and agriculture industry. The invention belongs to the technical field of wastewater treatment by photocatalytic oxidation. The magnetic photocatalyst containing oxide components of Fe2O, TiO2 and La2O3 is obtained by the co-precipitation-calcination method. Mixed titanium and lanthanum dioxide is used as an intermediate coating, over which a layer of Fe2O3 is deposited. The magnetic photocatalyst can be activated in the presence of sunlight, being used to treat water impure with organic compounds from the pharmaceutical industry or agricultural water_._
