Electrochemical treatment of waste solutions containing ferrous sulfate by anodic oxidation using an undivided reactor

Abstract

This paper describes an analysis of the performance of an electrochemical undivided reactor for the recycling of waste solutions containing ferrous sulfate. The effect of oxygen evolution as side anodic reaction on the figures of merit of the reactor is studied. The results suggest that the anode potential must represent a compromise between the increase in space time yield and the increase in the specific energy consumption. Experimental data are correlated with a mathematical treatment based on the stirred tank model.
