The traditional ion-exchange membranes face the trade-off effect between the ion flux and perm-selectivity. which limits their application for selective ion separation. Herein. we amalgamated various amounts of the ZSM-5 with the polyvinyl alcohol as ions transport pathways to improve the permeability of monovalent cations and exclusively reject the divalent cations. https://www.getpureroutine.com/limited-deal-swisse-ultiboost-high-strength-magnesium-powder-berry-180g-supply-top-savings/
