BACKGROUND Plasma albumin has been considered as important for governing glomerular permselectivity as well as being tubulotoxic in proteinuric states. The purpose of this study was to examine glomerular permselectivity and protein clearance of plasma albumin-deficient Nagase analbuminaemic rats (NAR) in normal and proteinuric states associated with puromycin aminonucleoside nephrosis (PAN) and...

In this paper, the variation of permselectivity in the course of concentration polarization is systematically analyzed for a three-layer membrane system consisting of a nonperfectly permselective ion exchange membrane, homogeneous or heterogeneous, flanked by two diffusion layers of a binary univalent electrolyte. For a heterogeneous membrane, an ionic transport model is proposed, which is amen...

Abstract Graphene oxide (GO) membranes have been proved to be ion-selective thanks their oxidized functional groups, which are naturally present on its surface. This ion selectivity, together with good mechanical strength, low cost, and simple synthesis, makes GO a great alternative material conventional costly polymers for the production of ion-exchange membranes. work focuses how produce as s...

In this study, ion exchange nanocomposite membranes was prepared by addition of Mg(OH)2 nanoparticles to a blend containing sulfonated polyphenylene oxide and sulfonated polyvinylchloride via a simple casting method. Magnesium hydroxide nanoparticles were synthesized via a facile sono-chemical reaction and were selected as filler additive in fabrication of ion exchange nanocomposite membranes. ...
