To improve the photoeatalytic efficiency of TiO2 for amoxicillin removal, a series of precious metals catalysts (M/TiO2, M = Ru, Rh, Pd, Ag, Ir, Pt or Au) were prepared by light deposition method. The synergistic photocatalytic activity of M/TiO2 with KBrO3 for degradation of amoxieillin (20 mg/L) in aqueous solution was researched under UV light (365 nm). The effects of metal loading, catalyst concentration, KBrO3 concentration and pH on the photoeatalytie activity of Rh/TiO2 with KBrO3 were explored. The results show that the photoeatalytie activity of M/TiO2 is closely related to its work function and KBrO3 has a greatly synergistic role on M/TiO2. Under the conditions of 0.1% Rh loading, Rh/TiO2 concentration of 0.15 g/L, KBrO3 concentration of 0.5 mmol/L and reaction liquid pH value at 5, the amoxicillin can be degradated completely within 90 min. Furthermore, the results of kinetic study show that the degradation reaction can be expressed by the first-order reaction kinetic model. [ABSTRACT FROM AUTHOR]
