Study on the Color Change Resistant Property of Silver and Zinc-loading Zeolite 4A Antibacterial Agent
载银锌4A沸石抗菌剂抗变色性能的研究

The color change resistant properties of silver and zinc-loading zeolite 4A antibacterial agent with varying contents of Ag+ and Zn2+ were investigated. The contents of Ag+ and Zn2+ of the specimens were determined by ICPS, the morphology and structure of the specimens were characterized by using X-ray diffraction (XRD), Infrared spectrum (IR) and High-Resolution Transmission Electron Microscope (HRTEM) techniques. The color change resistance properties and antibacterial performance of the specimens were examined. The results show that the color change resistance properties of the specimens are enhanced by increasing the content of Zn2+ and reducing that of Ag+ in silver and zinc-loading zeolite 4A antibacterial agent, meanwhile the antibacterial properties of the antibacterial agents are influenced little. On considering the cost, the antibacterial performance and the color change resistant properties, it is suitable for the contents of Ag+ and Zn2+ in the antibacterial agent are 0.41wt% and 3.83wt%, respectively.
