Abstract

The removal of two different heavy metals in aqueous solutions was investigated with polyamide nanofiltration membrane SNTE
NF270-2540, the results show that the retention of iron ions was total (100%). Depending of the experimental conditions, the retention
of copper ions was varied from 82% to 94%. It was observed that the pH has no influence in the iron retention. The retention of ions by
nanofiltration was done by Donnan effect (electrostatic repulsion) and counter-ion volume effect (steric exclusion).
