Separation of uranium from neodymium in a mixture of their oxides

Abstract

A detailed study has been made of the extraction and separation of uranium and neodymium by poly(hydroxamic acid) resin and tributyl phosphate (TBP) from solutions containing mixtures of these elements. Satisfactory separation schemes were achieved after determining the ion-exchange capacity of the resin for both elements in addition to the distribution coefficient of the elements between TBP and the aqueous solution. After separation, uranium was measured potentiometrically or spectrophotometrically and neodymium was measured by atomic absorption spectrometry.
