Abstract
A systematic study was conducted in a small laboratory aluminium cell with SnO2-based inert anodes, to determine the current efficiency (CE). The curr ent efficiency was determined by measuring the total amount of oxygen evolv ed at the anode. The influence of temperature, current density and interpol ar distance was,evaluated. The quantitative interdependences and the corres ponding calculated equations as well as the ranges of CE optimal values wer e established. High values of 93-96% obtained for CE indicate that SnO2-bas ed inert anodes could be more performant than the conventional carbon ones.
