VOLTAMMETRY FOR THE ION TRANSFER THROUGH A MEMBRANE

The voltammogram, VITTM, is introduced for the transfer of an ion, i z , from one aqueous solution, W1, to the other aqueous solution, W2, through a membrane, M, of organic solution (Org). The voltammogram is considerably different from that for the transfer of i z at the W/Org interface, VITIES, as follows; (1) The potential window observed in VITTM is about the twice of that in VITIES. (2) The slope of a reversible ion transfer wave in VITTM is much smaller than that in VITIES
