title: A novel approach for the design of a highly selective sulfate-ion-selective electrode.
abstract: A hydroxyl Schiff base molecule was synthesized from tetraethylenetetramine and 4-nitrosalicylaldehyde and explored as an ionophore with ionic liquid, cation excluder in PVC membranes showing remarkable sulfate selectivity; the optimal recognition site was predicted by density function theory (DFT) simulation.
