Regeneration of chelated polyvalent metal solutions by controlled potential electrolysis.

摘要

Electrochemical regeneration in an electrochemical cell of spent scrubbing solutions containing polyvalent metal chelates is accomplished without substantial degradation of the chelate by controlling the anolyte pH and maintaining the anode potential of the cell above the oxidation potential of the polyvalent metal chelate but below the oxidation potential of the chelate portion of the polyvalent metal chelate.
