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 effect of the modifier 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 modifiers of sensory and membrane compositions. The transport properties of unmodified and modified polyaniline nanotubes of plasticized polyvinyl chloride membranes have been studied. The effect of the concentration of near-membrane aqueous solutions of antibiotics, modifier on transport properties has been established. Quantitative characteristics of membrane transport are estimated: permeability coefficient and ion flux.
