D.N. Ambare,Seraj A. Ansari,M. Anitha,Pankaj Kandwal,D.K. Singh,Harvinderpal Singh,Prasanta K. Mohapatra +6 more
TL;DR: In this article, non-dispersive solvent extraction (NDSX) of Nd(III) from nitric acid feed solutions was carried out for the first time employing a hollow fiber contactor which used a mixture of di-nonyl phenyl phosphoric acid (DNPPA) and tri- n -octylphosphine oxide (TOPO) in petrofin as the carrier extractant.

Extraction of neodymium from nitric acid feed solutions using an emulsion liquid membrane containing TOPO and DNPPA as the carrier extractants
TL;DR: In this paper, the effect of different physical and chemical parameters such as stirring speed, neodymium concentration, external phase nitric acid concentration, extractant concentration and external to internal phase volume ratio, stripping agent concentration has been investigated on the extraction of Nd(III).
