摘要
以化学沉淀法制备得到多孔纳米SiO2，采用吸附法在其表面负载银，用载银的粉体抑菌囤直径表征抗菌性能。研究了吸附时间、硝酸银浓度及吸附温度与负载量的关系，并考查了焙烧温度与抗菌性能的关系。
Silver was loaded on porous nanometer SiO2 surfaces, which was prepared hy chemical precipitation method preparation, antibacterial performance was characterized by the antibacterial circle diameter of the loading silver powder. The relations of the adsorption time, the silver nitrate concentration, the adsorption temperature and the loading capacity were studied, and the relation between the temperature and the antibacterial performance was also examined.
