Preparation, characterization and alkali metal ion permeation through cross-linked poly(styrene-co-maleic acid) membranes

Membranes were prepared from poly(styrene‐co‐maleic acid) under different conditions and characterized by measuring thickness, swelling, electrical resistance, membrane potential and permselectivity. Permeability coefficients of KCl, NaCl, Na2SO4, NaOH, urea and creatinine were evaluated from dialys...

Description
Summary:Membranes were prepared from poly(styrene‐co‐maleic acid) under different conditions and characterized by measuring thickness, swelling, electrical resistance, membrane potential and permselectivity. Permeability coefficients of KCl, NaCl, Na2SO4, NaOH, urea and creatinine were evaluated from dialysis experiments. The charged membranes facilitated the active transport of alkali metal ions under a pH gradient. The energy for this movement comes from the simultaneous counter transport of protons.
