Abstract

Reversible bicarbonate and carbonate liquid|liquid ion transfer processes from aqueous solution into an organic 4-(3-phenylpropyl)pyridine phase are driven electrochemically with TPPMn(III/II) and shown to be facilitated over a wide pH range by 2-naphthylboronic acid (bicarbonate transfer potential -0.08 V vs. SCE; binding constant K(AB) = 10 2 mol(-1) dm(3) and carbonate dianion transfer potential 0.07 V vs. SCE; binding constant K(AB2) = 2 x 10(10) mol(-2) dm(6)).
