采用溶胶-凝胶法制备出含镥铜型无机抗菌材料。通过单因素实验得到较佳的制备条件,运用傅里叶变换红外光谱仪(FTIR)、X射线衍射仪(XRD)、扫描电镜(SEM)对制备出来的铜-镥无机抗菌材料进行表征;并对不同条件下制备出的材料进行比较。结果表明,在Lu3+浓度为0.005mol/L,反应时间为1h,反应温度为90℃的条件下所制备的材料,结构松散,分散性好;粒径分布为3～6μm,且均一。 The copper-containing inorganic antibacterial material containing Cu was prepared by sol-gel method. The best preparation conditions were obtained by single factor experiment. The prepared copper - 镥 inorganic antibacterial materials were characterized by Fourier transform infrared spectroscopy (FTIR), X - ray diffraction (XRD) and scanning electron microscopy (SEM) Materials prepared under different conditions were compared. The results show that the material prepared under the condition of the concentration of Lu3 + 0.005mol / L, the reaction time of 1h and the reaction temperature of 90 ℃ has the advantages of loose structure and good dispersibility. The particle size distribution is 3 ~ 6μm and uniform.
