Abstract

In present work, the anti-bacterial effect of silver/activated carbon (Ag/C) composites prepared by the ${\gamma}$-irradiation of $AgNO_3$ solution on Escherichia coli (E. coli) has been studied. Characteristics of the Ag/C composites were identified by scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic absorption spectroscopy (AAS). The inhibitory concentration of E. coli was found to be 0.387 ppm and the sterilizing concentration for the tested organism was 1.017 ppm. These results support the evidence that Ag/C composites have strong antibacterial activity to E. coli.

Keywords
