Component determination of extracted complex triphenylphosphin oxide ytri from nitric acid.

Abstract

The sudy on solvent extraction of rare earth elements such as Nd, Y from nitric  acid solutions with triphenylphosphin oxide (TPPO) has been studied. The influence of various factors such as concentrations of Triphenylphosphin oxide, nitric acids and rare earth elements on the distribution coefficient been studied. The formulation of extracted complex has also been presented by using the method of ICP analysis [2].
