Antibacterial silver/vermiculites and silver/montmorillonites
Original language description
The reason for the preparation and characterization of the novel antibacterial silver/vermicullites (Ag/V) together with the silver/montmorillonites (Ag/M) was that the information on the vermiculite structure change and stability of Ag/V in water as well as its effect on bacteria are sporadic. Transmission electron microscopy showed that the silver nanoparticles size distribution was much narrower for the samples Ag/M than for Ag/V. The mean size of the Ag particles was between 40 and 50 nm. Although the Ag nanoparticles did not adhere sufficiently at the clay minerals surface and migrated moderately into water, all samples under study were approved to be effective inhibitors of the bacterial growth persisting for th whole testing period of six days.Silver/vermicullite was antimicrobial more efficient againts K. pneumoniae and P. aeruginosa than silver/monmorillonite.
