以Al2O3为载体,采用离子吸附法制备了载银Al2O3抗菌剂,研究了其制备工艺如银离子掺量、反应温度、煅烧温度等对抗菌性能的影响,找出了最佳制备方法,并利用XRD结合离子溶出浓度的测试分析了其高温抗菌性能的变化。实验结果表明,采用离子吸附法制备的载银Al2O3抗菌剂具有优异的抗菌性能,其最佳制备工艺是银离子掺量为6%,搅拌时间为6h,煅烧温度为1000℃,其抑菌圈的宽度可以达到3.5mm。 The Al2O3-based antimicrobial agent was prepared by ion-adsorption method using Al2O3 as support. The effects of preparation technology such as silver ion content, reaction temperature and calcination temperature on the antibacterial activity were studied. The best preparation method was found out, XRD combined with ion elution concentration of the test analysis of its high temperature antibacterial properties. The experimental results show that the silver-loaded Al2O3 antibacterial agent prepared by ion adsorption has excellent antibacterial properties. The optimal preparation process is 6% silver ion concentration, 6h stirring time, 1000 ℃ calcination temperature, The width can reach 3.5mm.
