Evaluation of structural and charge properties of a polyamide nanofiltration membrane
Original language description
A polyamide thin-film composite NF membrane (AFC 80) was characterized in the present work by two different techniques: modelling of the rejection of uncharged solutes and modelling of the salt rejection. The interpretation of the data from uncharged solutes rejection experiments by using Donnan steric partitioning pore model (DSPM) allows determining the structural characteristics of the AFC 80 membrane. The experimental data for sodium chloride rejection were used to calculate the effective fixed charge density by means of an irreversible thermodynamics model (Spiegler-Kedem model) and of a charge model, namely Teorell-Meyer-Sievers (TMS) model. It was found that the membrane charge depends on the salt concentration in solution, this behaviour beingattributed to ion adsorption on the membrane. The dependence of the charge density on NaCl concentration obeys a Freundlich isotherm equation.
