A comparative study on the coordination of diglycolamide isomers with Nd(iii): extraction, third phase formation, structure, and computational studies.

ABSTRACT: A novel asymmetric diglycolamide N,N-dimethyl-N',N'-dioctyl diglycolamide (L^II) was synthesized. The Nd(iii) extraction behavior from HNO₃ and loading capability of the solution of L^II in 40/60 (v/v)% n-octanol/kerosene were studied. Analyses by the slope method, ESI-MS, and FT-IR indicated that, similar to the previously studied isomer ligand N,N'-dimethyl-N,N'-dioctyl diglycolamide (L^I), 1 : 3 Nd(iii)/L^II complexes formed. Under the same experimental conditions, the distribution ratio and limiting organic concentration of L^II towards Nd(iii) were smaller than those of L^I, but the critical aqueous concentration of L^II was larger, which impl
