摘要: Abstract In this study, the sliver nanoparticles (AgNPs) immobilized on sintered activated carbon (Ag/SAC) were synthesized by ultrasonic-assisted impregnation method and characterized scanning electron microscope (SEM), X-ray diffraction (XRD) nitrogen adsorption. SEM showed that AgNPs well embedded in SAC immersion time had an important influence final morphologies of AgNPs. Longer immersing duration caused significant aggregation The XRD data revealed successful synthesis immobilizing active did not change crystalline degree SAC. Texture characteristics determined analysis N 2 /77 K isotherms. minimum inhibitory concentration (MIC) Ag/SAC against Escherichia coli (DH5α) Staphyloccocus aureus (ATCC 29213) was evaluated a broth dilution method. MICs such as 5 mg/L (against E. ) 10 mg/L S. suggest have predominant antibacterial activity compared to carbon.
