Selective cation-exchange separation of lead on tin(II) hexacyanoferrate(III) gel

Abstract

Tin(II) hexacyanoferrate(III) gel, prepared by adding tin(II) chloride to potassium hexacyanoferrate(III) solution and heating at 80 °C, has been found to be stable in acids and salt solutions. Distribution coefficients, determined for various metal ions, show that the exchanger has a high affinity for lead. Binary separations of lead from a number of other metal ions at different concentrations were achieved on the column of the exchanger and a ternary separation of Pb2+- Cu2+- Zn2+ was also carried out.
