Preparation and Performance of Zinc Zeolite-Ce/TiO2 Antibacterial Material
Zinc zeolite-Ce/ TiO2 antibacterial material was prepared through immersion method with anatase nano- TiO2 power as main raw materials, zinc zeolite as carrier and cerium ions as doping ions. Its antibacterial function was evaluated by detecting the inhibition zone, the light-catalyzed effect of pure TiO2 antibacterial material was contrasted with zinc zeolite-Ce/ TiO2 antibacterial material by using ultraviolet spectrum. The results showed that zinc zeolite-Ce/ TiO2 antibacterial material had strong bacteriostasis to escherichia coli. It performed best when the diameter of inhibition zone reached to 34.64 mm under the condition of the ratio of nano-TiO2 to cerous nitrate was 40:1, the reacting time was half an hour, the maturing temperature was 300°Cand pH value was equal to 3.
