Abstract

Natural stellerite in Guangxi was used as raw material to prepare type-A zeolite;and the method of ion exchange was applied to prepare potassium diformate-loaded antibacterial agent which was characterized by XRD and SEM spectrometry.The results showed the type-A zeolite had good graft adsorption capacity to potassium diformate.Taking colony count method on type-A zeolite antimicrobial agent for antibacterial experiment,the results showed that the best absorbance value of Escherichia coli colony count was 0.500～0.700.The inhibition rate of antibacterial agent on E.coli could reach to 89.5%.
