doi:10.7517/j.issn.1674-0475.2005.05.382

Abstract

Abstract: Ag/TiO₂ loaded membrane was prepared with TiO₂ loaded polypropylene membrane as its carrier. Photo-reduction technology was used to reduce silver in AgNO₃ water solution of a certain concentration. The antibacterial and photocatalytic specificity of Ag/TiO₂ polypropylene membrane, TiO₂ polypropylene membrane and active carbon polypropylene membrane was studied under room light and sunlight. The result showed that Ag/TiO₂ loaded membrane exhibited good antibacterial property,because it had the activity of both the Ag and TiO₂. No matter when it was under room light or under sunlight, there were no live microbes examined. By examining the photocatalytic specificity of Ag/TiO₂ and TiO₂ loaded membrane, it was found that the ability of Ag/TiO₂ loaded membrane to photocatalyze methyl orange had been increased by 10% compared with that of TiO₂ loaded membrane which showed that Ag/TiO₂ membrane had good photocatalytic specificity.

Key words: Ag/TiO₂ polypropylene membrane, photo-reduce, antibacterial, photocatalytic property
