Microbial mortality behavior promoted by silver (Ag + /Ag o )-modified zeolite-rich tuffs for water disinfection

ConclusionTheE. coli,S. faecalis andC. albicans survival behavior suspended in aqueous solutions after contact with Ag-modified natural zeolites depends on the chemical speciation of the silver present in these materials, Ag+1 in the case of OAgiZ or nanoparticles of Ago promoted by the grapefruit extract (OAgnpTZ), as well as by non-thermal plasma generated in a dielectric barrier discharge reactor of parallel plates (OAgnpPZ). In general, the concentration of silver in the aqueous solution after the disinfection process cannot exceed the recommended levels established for international organizations. The OAgnpPZ is a potential microbicide agent againstE. coli andC. albicans, and the OAgnpTZ forF. faecalis.Graphical abstractARTWORK.
