| 摘 要： | 在AgNO3溶液中添加NaCl溶液，形成胶体悬浮液，利用化学沉积法制备胶体氯化银膜。在胶体氯化银膜表面分别添加大肠杆菌(E．coli)和青霉菌(penicillium)孢子悬浮液，在近紫外条件下，研究胶体氯化银膜的抗菌性能和光催化特性。结果表明，胶体氯化银膜在近紫外条件下，能够产生大量的羟基自由基，对大肠杆菌和青霉菌显示了强大的杀菌特性。经聚氯乙烯(PVC)固定的胶体氯化银膜，在低光强度下经连续30个批次的光照杀菌，对大肠杆菌和青霉菌杀菌效果几乎没有变化，证明胶体氯化银膜在近紫外条件下的杀菌稳定性和实用性。

| Abstract: | NaCl aqueous solution was added into AgNO 3 solution to generate colloidal suspension,and colloidal AgCl film was prepared by chemical sedimentation.E.coli suspension and penicillium suspension were added onto the surface of colloidal AgCl film respectively.Under near UV light condition,characterization of antibacterial and photo catalytic deggradation of colloidal AgCl film was studied.The results showed that a great amount of hydroxyl radicals in aqueous solution produced by photochemical catalysis of colloidal AgCl film under near UV light displayed a strong antibacterial performance.Colloidal AgCl film immobilized by PVC did not affect the killing effects of E.coli and penicillium after it was illuminated under low light intensity to kill about 30 batches of bacteria.The results confirmed the sterilization stability and applicability of colloidal AgCl film under the near UV light. |
