摘要/Abstract

摘要： 以4A沸石为载体, AgNO3溶液为反应液,通过离子交换法,制备载银沸石抗菌剂.探讨了制备工艺对沸石交换性能的影响;通过X射线衍射分析表征了样品的结构,并对其抗菌性能进行了测定.结果表明:交换液的浓度、反应温度、反应时间、pH值等对沸石的交换性能有较大的影响;交换液浓度为0.1mol/L、pH值为6-8为宜,从能耗角度考虑,室温为宜,但从反应时间考虑,应该选用加热;样品对大肠杆菌、沙门氏菌具有良好的抗菌性能.

关键词: 载银沸石抗菌剂, 制备工艺, 抗菌性能

Abstract: 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.

Key words: zeolite silver-supported antibacterial agent, preparation process, antibacterial performance
