N-Substituted amides possess excellent properties for the separation of niobium and tantalum.This paper describes a study on the mechanism of the extraction of niobium and tantalum by a solution of N, N-di-sec-octylaoetamide (DOAA) or N-mono-sec-octylacetamide (MOAA) in xylene from the HF-H2SO4 system.
