Antagonism in the aggregation behaviour of N,N,N′,N′-tetraoctyldiglycolamide in n-dodecane upon adding N,N-dioctylhydroxyacetamide during trivalent metal extraction

The solvent phase composed of tetraoctyl diglycolamide (TODGA) in n-dodecane (n-DD) undergoes the undesirable organic phase splitting during the solvent extraction of trivalent actinides and lanthanides from nitric acid medium. To overcome this limitation a neutral extractant namely the N,N-dioctyl hydroxyacetamide (DOHyA), which was half the molecule of TODGA, has been added to the solvent phase and evaluated for the extraction of Nd(III) from...
