| Popis: |
The study took zeolite X as carrier and chitosan as intermediate to compound dimethyl potassium to prepare zeolite X antimicrobial agent by hydrothermal synthesis. The best condition to prepare zeolite X antimicrobial agent is: Mass ratio of zeolite X:Chitosan:dimethyl potassium is 3:1:2, temperature is 40 °C and time is 2 h. Through antibacterial test, we can see that the best inhibitory rate is 78.16%, and release effect significantly enhanced. We studied the structure of zeolite X antimicrobial agent by IR, XRD, SEM, XPS. It can be concluded that: The H on amino-group of chitosan can form hydrogen bonds with O on dimethyl potassium and zeolite X and the hydrogen bonds Play a major role in connecting dimethyl potassium and zeolite X; Free hydroxyl on zeolite X can form hydrogen bonds with O in C-O of chitosan. And it may form hydrogen bonds with O in C=O of dimethyl potassium. And explain the reason of improving of antimicrobial. |
