Abstract

Factors affecting the efficiency of electrochemical recovery of EDTA and Pb(II) from their chelated solutions were systematically examined using a cation exchange membrane Neosepta CM-1. The catholyte contained an equimolar amount of Pb(II) and EDTA, and the anolyte contained 0.1M NaNO₃. The iridium oxide coated on titanium (IrO₂/Ti) and stainless steel were used as anode and cathode, respectively. Experiments were carried out at different current densities (46.3-185A/m²), initial catholyte pH values (1.47-6.02) and Pb(II) concentrations (0.005-0.03M). An economically feasible current efficiency and recovery percentages of Pb(II) and EDTA could be achieved if the concentration of the chelated Pb(II) was sufficiently high.
