Sulfur analogs of imidodiphosphoric acid as extractants
TLDR
In this paper, the distribution of Ag, Zn, Cd, Sc, Eu, Hg, and Hf between mineral acids (HNO 3, HCl) and benzene solutions of selected sulfur derivatives of organophosphoric reagents containing the (RO 3 )PS group (X = O, S) was examined.Abstract:
The distribution of Ag, Zn, Cd, Sc, Eu, Hg, and Hf between mineral acids (HNO 3 , HCl) and benzene solutions of selected sulfur derivatives of organophosphoric reagents containing the P(X)NHP(X) or (RO 3 )PS group (X = O, S) was examined. The effect of the organic solvent was also investigated for Hg and some of the reagents. The composition of the complexes extracted was identified, and the corresponding extraction constants were calculated.read more

Solvent extraction of americium by imidodiphosphates and diimidotriphosphates
TL;DR: In this paper, the results of solvent extraction were described for determining the americium content in the liquid samples and the properties of tetraphenyl imidodiphosphates and their sulphur analogues for trivalent americium in the presence of trin-n-octylphosphine oxide (TOPO) were investigated.
