【摘要】：通过溶胶-凝胶法制备出Zn-Eu抗菌白炭黑,该产品是一种含有稀土Eu~(3+)的新型无机抗菌材料,与只单载Zn~(2+)的抗菌白炭黑相比,该新型无机抗菌材料的抗菌性能更加显著。通过单因素实验探究Zn~(2+)浓度、Eu~(3+)浓度和反应时间对产品杀菌率的影响,得到最佳制备方案:Zn~(2+)浓度为0.8 mol·L~(-1)、Eu~(3+)浓度0.005 mol·L~(-1)、反应时间1 h。最佳条件下制备得到抗菌性能优良的Zn-Eu抗菌白炭黑,并对其进行FTIR、SEM和ICP-OES表征。FTIR结果显示,Zn~(2+)和Eu~(3+)加入后没有明显改变载体白炭黑的基本结构。SEM和ICP-OES分析表明,Zn-Eu抗菌白炭黑粒径较小,分散性较好并且Zn~(2+)和Eu~(3+)均担载在了载体白炭黑上。
[Abstract]:Zn-Eu antibacterial silica was prepared by sol-gel method. The product is a new inorganic antibacterial material containing rare earth Eu~(3, which is compared with the antibacterial silica containing only Zn~(2). The antibacterial properties of the new inorganic antibacterial material are more remarkable. The effects of Zn~(2 concentration and reaction time on the bactericidal rate of the product were investigated by single factor experiment. The optimum preparation method was obtained: the concentration of 0. 8 mol 路L ~ (-1) ~ (1) ~ (?) (0. 005 mol 路L ~ (1)) mol 路L ~ (1) ~ (-1). Zn-Eu silica with excellent antibacterial properties was prepared under the optimum reaction time of 1 h. The results of FTIR and FTIR showed that the silica was characterized by FTIR SEM and ICP-OES. Zn~(2) and Eu~(3) did not obviously change the basic structure of carrier silica. SEM and ICP-OES analysis showed that Zn-Eu antibacterial silica particle size was smaller. Zn~(2) and Eu~(3) were loaded on the carrier silica.
