Resumo: Anodic limiting currents were measured in an unstirred divided cell at an inclined small scale anode using a large scale cathode with angles of inclination from vertical axis as 45, 60 and 75°. Anode heights (II) vary from 1 cm to 6 cm and phosphoric acid concentration from 6 to 10 moles. Limiting currents for electropolishing of copper were between 5 and 58 mA.cm-2 depending on the operating conditions. A general correlation of data of all inclinations was obtained using the equation: I = 28.57(Θ0.520.C -0.89.H -0.91) with an average deviation of ±4%.
