摘　　要：将铕和金属银离子共同掺杂到白炭黑中,制得一种含稀土新型无机抗菌材料。通过单因素实验得到最佳制备条件为,铕浓度0.005 mol·L-1,反应温度90℃,反应时间1 h。在此条件下制得的铕-银共掺杂抗菌白炭黑对大肠杆菌具有很好的杀菌效果,杀菌率达98%以上。采用XRD、SEM、EDS和FTIR等手段对所制备的样品进行结构形态表征,结果表明产品为无定形态,铕以两种形态存在于材料中,一种与银共生,附着在载体白炭黑上,另一种则游离在材料中,铕和银的添加并没有明显改变白炭黑原有的结构。A new inorganic antibacterial material was synthesized with white carbon black as the carrier, silver inos as antibacterial agent and europium nitrate as additives by a sol-gel method. The optimal conditions were dertermined as concentration of europiam nitrate 0. 005 mol ·L^-1, reaction temperature 90℃ and reaction time 1 h. Bacteriostasis rate was over 98% in the above conditions. The as-synthesized antibacterial material was characterized by X-ray diffraction （XRD）, scanning electron microscope （ SEM ）, energy dispersive spectrometer （EDS） and Fourier transform infrared （FTIR）. The result showed that the product of Eu-Ag codoped antibacterial white carbon black was amorphous. There were two forms for europium in the material：one is in symbiosis with silver adhered to the carrier white carbon black, and another was free in the material. The structure of Eu-Ag codoped antibacterial white carbon black and white carbon black was similar.
