Physico-chemical characteristics and sorption activity of carbon, organosilica sorbents and their modi ed forms towards proteins, possessing speci c activity, and cholerae vibrio have been studied. It was found, that carbon materials modi ed by copper (II) e¬ectively extracts cholerae vibrio (100%) and may be recommended for disinfection of drinking water. Sorption capacity of organosilica sorbents and their modi ed by copper (II) forms towards pathogenic micro®ora (E.coli, St.aureus, Ps.aeruginosa) depending on the composition of the sorbents, concentration of the modi ed reagent, pH of medium have been evaluated. The rows of the increase of sorption of pathogenic microorganisms by synthetic sorbents in water-salt solutions were established: Al(III) < Zn(II) < Cu (II). It was shown that inhibiting e¬ect of modi ed synthetic organosilica and natural sorbents towards such pathogenic microorganisms as E-coli, St.aureus Ps.aeruginosa and fungus Bacillus pyocyaneus accordingly is equal 80{98%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
