Abstract

Electrolytic recovery of metals such as Cu(II) and strong chelating agents such as EDTA (ethylenediaminetetraacetic acid) from their equimolar complexed solutions was investigated in a stirred cell having a membrane separator. The iridium oxide coated on titanium (IrO₂/Ti) was used as the anode. Experiments were performed as a function of membrane-type (Neosepta CM-1 and CM-2), current density (18.5-185A/m²), cathode material (Pt plate, Pt/Ti, Cu plate, stainless steel), initial catholyte pH (1-9) and initial Cu-EDTA chelate concentration (0.01-0.08M), and initial anolyte NaNO₃ concentration (0.1-0.8M). An economically feasible current efficiency (>60%) and metal recovery (>95%) could be obtained if the Cu-EDTA chelate concentration was sufficiently high. Electrodeposition of other divalent metals including Pb, Hg, and Cd onto Pt/Ti cathode from their EDTA solutions was possible, but no apparent deposition of Co, Ni, Zn, and Mn was observed.
