摘　　要：通过调整抗菌剂中银、锌离子的含量,研究了载银锌4A沸石抗菌剂的抗变色性能.利用ICPS测定了样品的银、锌含量,通过XRD、IR、TEM表征了抗菌剂的结构和形貌,并对其抗变色性能和抗菌性能进行了测试和分析.结果表明,减少ZLSZ抗菌剂中银离子(Ag^+)的含量,增加锌离子(Zn^(2+))的含量,抗菌剂样品的抗菌性能变化不大,而抗变色性能却大幅度提高.从抗菌剂的成本、抗菌性能和抗变色性能等方面综合考虑,载银锌4A沸石抗菌剂中,银含量为0.41wt%,锌含量为3.83wt%为宜.The color change resistant properties of silver and zinc-loading zeolite 4A antibacterial agent with varying contents of Ag^＋ and Zn^2＋ were investigated. The contents of Ag^＋ and Zn^2＋ 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 Zn^2＋ 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 Zn^2＋ in the antibacterial agent are 0.41wt% and 3.83wt%, respectively.
