摘　　要：目的:制备钴-银纳米微粒,并初步探讨钴-银纳米微粒对细菌的抑制效果.方法:利用水热合成法制备出不同银含量的钴-银纳米微粒.运用扫描电子显微镜表征钴-银复合纳米材料,并评价其对常见细菌的杀灭效果.结果:钴-银复合微粒粒径约为10μm,银含量不同的钴-银复合纳米材料均显示出抑菌作用,尤其银含量高的钴-银复合纳米材料抗菌效果较好.钴-银复合纳米材料可以通过磁场力将其回收,钴-银纳米复合材料回收率为98%,回收的钴-银纳米复合材料仍有抑菌作用,并可以重复使用又可以减少对环境的污染.结论:制备的钴-银纳米微粒具有较好的抑菌活性和较高的回收率,回收得到的材料依旧有很好的抗菌效果.AIM： To study the preparation of cobalt-silver nanoparticles and its antibacterial activity. METHODS： Co-Ag composite nano-materials with different silver contents were prepared by hydrotherma synthesis. The scanning electron microscopy（ SEM） was used to characterize these products, whose antibcuterial effects on common bacteria were evaluated.RESULTS： The size of cobalt-silver nanoparticles is about10 μm. Co-Ag composite nano-materials with different contents of silver have good antibacterial efficacy. With the content of silver increased,the antibacterial effect becomes better. Co-Ag composite nano-materials can be recycled by the magnetic field,with a higher recovery rate of 98%. CONCLUSION： The recycled product also has the antibacterial effect. Co-Agcomposite nanomaterials not only has the higher recovery rate,but also can reduce the pollution to the environment.
