Abstract

The performance of a batch undivided electrochemical reactor with a rotating cylinder electrode of expanded metal sheets for the removal of tin from synthetic sulfate solution is studied. The effect of the cathode potential, initial tin concentration, number of sheets forming the cathode and cathodic side reactions on the figures of merit of the reactor is analysed. For a cathode potential of −0.65 V vs SCE at 500 rpm, the tin concentration decreased from 393 to 94 mg l−1 after 30 min of electrolysis with a specific energy consumption of 3.93 kWh kg−1 and a normalized space velocity of 1.27 h−1. The change in concentration was higher when the potential was more negative because of the turbulence-promoting action of the hydrogen evolution. The results suggest that the applied potential must represent a compromise between the increase in space time yield or normalized space velocity and the increase in the specific energy consumption.
