Popis: The removal of two different heavy metals in aqueous solutions was investigated with polyamide nanofiltration membrane SNTENF270-2540, the results show that the retention of iron ions was total (100%). Depending of the experimental conditions, the retentionof 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 bynanofiltration was done by Donnan effect (electrostatic repulsion) and counter-ion volume effect (steric exclusion).
