【 摘 要 】

The silver was deposited on the surface of titanium dioxide (TiO2) here, and the silver was presented in its elemental form. The antibacterial composite material prepared by liquid phase precipitation method in this study has a 98.69% yield with silver loaded efficiency of 98%. The content of silver in the composite material was 2.8% determined by titration. Antimicrobial effect of the synthesized composite material was carried out against gram-negative bacteria (E. coli) and gram-positive bacteria (S. aureus) by using the zone of inhibition method. The synthesized Ag-TiO2 showed enhanced bactericidal activities in compare with TiO2.
