Preparation and Antibacterial Performance of Zeolite Loaded Silver Antibacterial Agent

The silver-supporting antibacterial zeolite was prepared by the ion exchanging method with zeolite as the carrier and AgNO3 solution as the exchanging solution. The influence of preparation process on exchanging ability of zeolite was studied and the optimum preparation process was determined. The structure was characterized by X-ray diffraction (XRD) and the antibacterial ability was tested. The results show that the exchanging ability is greatly influenced by the concentration of exchanging solution, temperature, time and pH values. The suitable concentration of exchanging solution is 0.1mol/L. The pH value should be controlled between 6~8. In view of energy consumption, ambient temperature is appropriate, but in view of reaction time, the reaction should be heated. The silver-supporting antibacterial zeolite has an excellent antibacterial performance against E.coli and S.faecalis.
