| 摘 要： | 研究了载银黄腐酸抗菌剂的制备及其抗菌效果。通过在水溶液中黄腐酸与银粒子之间的络合作用得到了载银黄腐酸抗菌剂。红外光谱分析表明黄腐酸与Ag~+粒子发生了络合反应。热重分析结果显示载银黄腐酸的热稳定性大大提高。将载银黄腐酸抗菌剂添加到聚乙烯醇中得到了抗菌塑料。抗菌实验表明加入载银黄腐酸抗菌剂的聚乙烯醇塑料对枯草杆菌和大肠杆菌均表现出良好的抗菌性能。

| Abstract: | Preparation and antibacterial activity of silver-loaded fulvic acid antibacterial agent were studied. Silver-loaded fulvic acid antibacterial agent was prepared by the complexation between Ag+ ions and fulvic acid in aqueous solution. IR characterization proved the formation of fulvic acid-Ag+ complexes, and thermogravimetric analyses showed that the fulvic acid-Ag+ complexes exhibited higher thermal decomposition temperature than fulvic acid. The fulvic acid-Ag+ complexes were blended with polyvinyl alcohol to obtain antimicrobial plastics. Antibacterial experiments approved that PVA plastics had excellent bacteriostasis against Bacillus subtilis and Escherichia coli. |
