Interpretation of structure and electrical properties of a polyamide nanofiltration membrane
Original language description
A polyamide thin composite NF membrane (AFC 30) was used to characterize the structural and electrical parameters. The structural values were estimated with permeation experiments of aqueous solution of neutral solutes in conjunction with steric hindrance model (SHP). The fixed charge density on the membrane surface was determined using sodium chloride experiments at different concentrations. The data from sodium chloride experiment were used to evaluate the effective charge density (ФX) by using the Spiegler-Kedem model together with the charge model called Teorell-Meyer- Sievers (TMS). It was found that the membrane charge depends solely on the salt concentration in the solution, which is because of ion adsorption on the membrane surface.
