Transport properties of unmodifi ed and modifi ed polyaniline nanotubes of amoxicillin-selective membranes

Abstract

The transport processes occurring in polymer matrix characterize their physico-chemical properties, determine the directions of practical application. The literature data on ion transport in plasticized polymer membranes and theoretical aspects of membrane transport are critically reviewed. The eff ect of the modifi er on the transport properties of membranes is shown. The article shows the possibility of implementing a new amoxicillin-selective plasticized membrane ([Ag(Amox)2 ]DMDSA), which includes a molecular imprinted polymer (MIP) – polyaniline nanotubes (PANI NT), which are of particular interest as modifi ers of sensory and membrane compositions. The transport properties of unmodifi ed and modifi ed polyaniline nanotubes of plasticized polyvinyl chloride membranes have been studied. The eff ect of the concentration of near-membrane aqueous solutions of antibiotics, modifi er on transport properties has been established. Quantitative characteristics of membrane transport are estimated: permeability coeffi cient and ion fl ux.
