TL;DR: A generic transurantc (TRU) element extraction/recovery process was developed based on the use of octyl(phenyl)-N,N-diiso-butylcarbamoylmetliylphosphine oxide, 0φD(iB)CMPO, dissolved in PUREX process solvent (tribntyl phosphate, TBP, in normal paraffluic hydrocarbon, NPH) as mentioned in this paper.

TL;DR: In this paper, the authors derived equations describing the permeability of a liquid membrane to metal cations taking into account aqueous diffusion, membrane diffusion, and interfacial chemical reactions as simultaneous permeability controlling factors.

TL;DR: A review of recent publications that have focused on combined extractant systems for separating trivalent actinides from the lanthanides is presented in this article, where the authors show that although there is significant potential for practical exploitation of mixed neutral/acidic extractant system to achieve a single-step separation of trivalents from acidic high-level waste solutions, the fundamental chemistry underlying these combined systems is not yet well understood.

TL;DR: The magnetically assisted chemical separation process (MACS) as discussed by the authors combines the selective and efficient separation afforded by chemical sorption with the magnetic recovery of ferromagnetic particles for treating the underground storage tanks at Hanford.

TL;DR: Tripodal chelates bearing three diglycolamide units precisely arranged on a triphenoxymethane platform were synthesized to mimic the preferred tricapped trigonal prismatic geometry favored by lanthanide with oxygen donor ligands, and the ligand binds heavier lanthanides very efficiently in acidic media.
