Abstract: Abstract In order to improve the selectivity of the AMX membrane, a polyethyleneimine (PEI) layer was adsorbed on its surface by the immersion of the considered membrane in a solution of PEI. The adsorption process of PEI was studied and the results were well correlated with the Langmuir model and with Lagergren's pseudo‐first‐order kinetic model. Equilibrium ion exchange isotherms of (Cl−/normalNO3−), (Cl−/normalSO42−), and (normalNO3−/normalSO42−) systems, using modified AMX membrane, were established at va…
