Abstract

The electrochemical regeneration of chromium containing solution obtained from metal finishing industry was carried out using different anode materials (lead & platinished titanium) and cathode materials (lead and stainless steel). Effect of different parameters like anode current density, catholyte concentration, temperature, and anolyte flow rate on current efficiency was studied. At current densities of 2-2.5 A/dm2 using lead as anode at temperature of 303-313 K and anolyte flow rate of 130 - 300 cm3/min, the current efficiency of 68 - 76% with an energy consumption of 3.0 to 3.2 kWh/kg CrO3 was achieved.
