Analysis of lead(II) retention from single salt and binary aqueous solutions by a polyamide nanofiltration membrane: Experimental results and modelling

► Separation of Pb(II) ions by nanofiltration using AFC 80 membrane. ► Modelling of the NF process using the Spiegler-Kedem model. ► Separation mechanism and analysis of the membrane transport process. ► Structural and electrokinetic characterisation of AFC 80 membrane. ► Effective removal of pollutants from mixtures simulating the real wastewaters.
