A型沸石抗菌剂的体外抑菌性能
Antimicrobial Properties in Vitro of Type-A Zeolite Antibacterial Agent
摘要
Abstract
Natural stellerite as raw material to prepare the type-A zeolite in the method of ion exchange can prepare the potassium diformate-loaded antibacterial agent, and be characterized by XRD and IR spectrometiy. The new product of type-A zeolite has a good graft adsorption capacity to potassium diformate. The sample powder is pressed into discs and used in the antibacterial experiment. The results show that a certain diameter of type-A zeolite antibacterial agent can be observed in five different kinds of bacteria. The strongest inhibitory works on E. coli. Concentration of hydrochloric acid by 0. 2 - 0. 3 mol ? L-1 can effectively improve the antibacterial activity of the new type-A zeolite antibacterial agent. The diameter of type-A zeolite antibacterial agent can reach 12. 43 mm.关键词
