Abstract
A series of titanium peroxide samples were prepared with the reaction of titanium sulfate solution and H2O2 solution on controllable preparation conditions and showed different adsorption properties on methylene blue. The optimum pH, highest temperature and volume of H2O2 is 9.0, 40 ± 2°C and 35 mL. The saturated adsorption capacities of the titanium peroxide for methylene blue, Cd (II), Cu (II), and Zn (II) were 263.25, 73.89, 73.54 and 41.83 mg/g at 25°C, respectively. The adsorption was rather fast. The controlling mechanism of adsorption processes could be electrostatic adsorption according to the characterization and adsorption results..
