Preparation method of solid titanium peroxide material for adsorption of cationic dye wastewater

The invention discloses a preparation method of a solid titanium peroxide material for adsorption of cationic dye wastewater, relating to the technical field of new material preparation. According to the preparation method of the solid titanium peroxide material, titanous sulfate, sulphuric acid, hydrogen peroxide, ammonium hydroxide and distilled water are used as main raw materials; main devices comprise a thermometer, a magnetic stirring apparatus and a thermostat water bath; the preparation method comprises the steps of using dilute sulphuric acid to prepare titanous sulfate solution with certain mass fraction, reacting with the hydrogen peroxide to generate a reddish brown solution, regulating the pH value of the reddish brown solution to be neutral to generate yellow solids, washing, standing and drying by distillation to obtain the solid titanium peroxide. The method has the characteristics that the raw materials are easily accessible, the method is simple and easy to operate, and the reaction conditions are mild; the prepared titanium peroxide powder is a mesoporous material and has strong adsorption property to cationic dyes.
