Square wave voltametry (SWV) has been successfully applied to arrays o
f liquid/liquid (L/L) microinterfaces formed across microholes perfora
ted on a polyester film. The study ClO4- ion transfer from water to 1,
2-dichloroethane (DCE) showed that the experimental parameters E(SW),
E(S), and f are identical to those found for the reversible electron t
ransfer on solid microelectrodes.
