Studies on Environmental Pollutants: Selective Separation and Recovery of Pb(II) on Ferric Phosphate Columns

Abstract

A new method is described for the recovery and selective separation of Pb(II). The following mixtures have been separated: Hg (II) -Pb (II), Zro(II) -Pb (II), Cd (II) -Pb (II), Cu (II) -Pb (II), Mn (II) -Pb(II), Zn (II) -Pb (II), Sr (II) -Pb(II) and Ni (II)-Pb (II), on ferric phosphate columns. Cu (II), Cd (II), Ni (II), Hg (II), Mn (II), Zn (II), Sr (II) and Zro(II) were eluted with 0.01M-NH₄NO₃ and Pb(II) with a mixture of 0.1M-HNO₃ + 1.0M-NH₄NO₃ solution. Proposed studies can be applied to pollution analysis and alloy analysis.
