Polyelectrolyte Complexes Consisting of [2-(Diethylamino)ethyl]clextran Hydrochloride, Glycol Chitosan, and Sulf ate of Poly(vinyl alcohol) The Compositions of Polyelectrolyte Complexes, and Active and Selective Transport of Alkali Metal Ions through the Membranet

Abstract

Polyelectrolyte complexes (PECs) consisting of [2-(diethylamino)ethyl]dextran hydrochloride, glycol chitosan, and the sulfate of poly(vinyl alcohol) have been prepared. The cornposition of the PEC was found to depend appreciably on the experimental conditions.
The PEC membrane prepared in a 2.27 mol.dm^-3 HCl solution was m ost resistant to alkaline and acidic environments. The transport behavior of alkali metal ions through this membrane was much affected by the hydrogen ion concentration providing the driving force, and especially by organic solvents. It is suggested that a change in the chemical and physical properties of the PEC membrane caused by a hydrogen ion concentration change, controls the active and selective transport through the membrane.
