The universal solvent extraction (unex) process. i. development of the unex process solvent for the separation of cesium, strontium, and the actinides from acidic radioactive waste
V. N. Romanovskiy,Igor V. Smirnov,Vasily Babain,Terry A. Todd,R. Scott Herbst,Jack D. Law,K. N. Brewer +6 more
TL;DR: A synergistic extraction mixture containing chlorinated cobalt dicarbollide (CCD), carbamoylmethyl phosphine oxide (CMPO), and polyethylene glycol (PEG) has been investigated for the simultaneous recovery of cesium, strontium, lanthanides, and actinides from highly acidic media as discussed by the authors.

Novel phosphorylated calixarenes for the recognition of f -elements
Maria D. Karavan,Maria D. Karavan,Françoise Arnaud-Neu,Véronique Hubscher-Bruder,Igor V. Smirnov,Vitaly I. Kalchenko +5 more
TL;DR: The binding properties of three series of phosphorylated calixarene derivatives bearing phosphine oxide or phosphonate groups either at the wide or the narrow rims have been investigated towards some representative lanthanide and actinide ions using several approaches: (i) liquid-liquid extraction of europium, americium, thorium and uranyl ions from nitric acid solutions into the two diluents m-nitrobenzotrifluoride (m-NBTF) or dichloromethane; (ii) complexation in single media (

V. N. Romanovskiy,Vasily Babain,M. Yu. Alyapyshev,Igor V. Smirnov,R. S. Herbst,Jack D. Law,Terry A. Todd +6 more
TL;DR: In this paper, the diamide derivatives of dipicolinamide (2,6−pyridinedicarboxylamide or DPA, (R′R″NCO)2C5NH3) in mixtures containing chlorinated cobalt dicarbollide in the acid form (HCCD), with and without a substituted polyethylene glycol (PEG), have been investigated.
