锌-钬共掺杂无机抗菌材料的制备及性能研究

Preparation and Properties of Zinc-Holmium Inorganic Antimicrobial Materials

采用溶胶-凝胶法制备了一种新型无机抗菌材料--锌-钬抗菌白炭黑。通过单因素实验和响应曲面法优化,得到了最优制备条件为:锌浓度0.711 mol·L^-1,钬浓度0.5 mmol·L^-1及反应时间65 min。获得了分散性好、粒度较小、抗菌性能良好的复合抗菌材料。通过SEM,EDS,FTIR,粒径检测和抗菌检测等手段对锌-钬抗菌白炭黑进行了表征。结果表明:锌-钬抗菌白炭黑结构蓬松,平均粒径为28.948μm,且锌离子和钬离子的添加对载体白炭黑的结构基本没有影响,其抗菌率可达83.41%。

A new inorganic antibacterial material of zinc-holmium white carbon black was prepared by sol-gel method.The optimized preparation conditions were zinc concentration 0.711 mol·L^-1,holmium concentration 0.5 mmol·L^-1 and reaction time 65 min as controlling single factor experiments and response surface method design experiments.The composite antibacterial material owned the advantages of good dispersion and antibacterial performance,and small particle size.The antibacterial materials were characterized by SEM,EDS,FTIR,particle size,antibacterial assay.The results showed that the structure of zinc-holmium antibacterial materials is fluffy,the average particle size is 28.948μm,and the structure of carrier silica has not been influenced by addition of zinc ions and holmium ions.The antibacterial rate has reached 83.41%.
