STAINLESS STEEL WASTESⅡ. CO-REMOVAL OF FISSION PRODUCTS IN THE ELECTROLYTIC SEPARATION OF IRON, CHROMIUM, AND NICKEL AT A DROPPING MERCURY ELECTRODE

摘要

A study has been made of the removal rates of cesium, barium, strontium, yttrium, cerium, ruthenium, and zirconium as a function of electrode potential at a dropping mercury cathode. Removal was studied in sulfate solutions containing varying concentrations of iron, chromium, nickel, chloride, and acid. Results indicated that iron, chromium, and nickel can be removed from acidic sulfate solutions with good separation from all fission product ions studied except zirconium and possibly ruthe-nium. Polarographic half-wave potential data were obtained and tabulated together with minimum removal potentials for the fission product ions. A description of the mercury drop-washing polarographic cell used for studying removal of tracer amounts of radioisotopes is presented.
