Abstract

The title compound-octylphenyl acid phosphate/OPAP/ in toluene has been used for the systematic extraction studies of uranium/VI/ and some trivalent lanthanides from nitric acid medium. The effect of variables like nature of diluent and concentrations of nitric acid and OPAP on extraction has been investigated. Basing on the extraction data, optimum conditions for the separation of U/VI/ from Ce/III/, Nd/III/, Gd/III/ and Tb/III/ have been worked out.
