Abstract:

The four categories of antibacterial zeolites were prepared by different methods with 13X zeolite as their carrier, and their structures and properties were characterized by WAXD, EDS, AAS and bacteriostasis
circle tests. The results show that the basic structure of 13X does not change in the process of the cation exchange, and the cations absorbed by 13X can be slowly released into medium. The composite
metal zeolites contained Ag+ cations prepared by the method of composite cations exchange are optimum in antibacterial performance and superior to AGZ-330 antibacterial agent in their bacteriostasis
and cost. The composite metal ions zeolites have better slowly release effect and high content of cations killing bacterials more effectly due to their synergistic effect and broad spectrum antibacterial properties.

Key words: inorganic antibacterial material, 13X zeolite, composite metallic ions, slowly release effect, heat treatment, bacteriostasis circle test
