This paper deals with the study on the antibacterial activity of TiO2-doped Ag prepared from radiophotography wastewater. The antibacterial agent was prepared by reduction of Ag(I) in the radiophotography wastewater over TiO2 photocatalyst under UV light irradiation and characterized by EDS, XRD, SRUV, and TEM machines. The antibacterial activity in inhibiting the growth of Staphylococcus aureus was examined by counting the number of viable bacterial colonies using the TPC method. The result shows that Ag doping on TiO2 as TiO2-Ag can shift its absorption into the visible region. TiO2-Ag assigns better antibacterial activity compared to TiO2 under visible light irradiation. The efficiency of the antibacterial activity is found to be influenced by Ag loaded in the TiO2, irradiation time, and the antibacterial agent dose. The highest antibacterial activity is achieved by 100 mg/L of TiO2-Ag (2) under 3 h irradiation by visible light.
