Extraction of rare earth ions using thermomorphic ionic liquid: In situ spatial and temporal distribution combined with thermodynamic description

Stella Papadopoulou, Antonio de Souza Braga Neto, Isabelle Billard, Clément Cousin, Valérie Briois, Anthony Beauvois, Laurent Michot, Guillaume Mériguet, Anne-Laure Rollet, Juliette Sirieix-Plénet

Homogeneous Liquid–Liquid Extraction (HLLE) provides a valuable opportunity for recycling Rare Earth Elements (REE) by circumventing the liquid–liquid interface and avoiding the problems linked to the high viscosity of ionic liquids (IL). For optimizing these processes with the ultimate goal of…

Ion-specific effects in polyelectrolyte solutions: chain-chain interactions, chain rigidity and dynamics

Claire Hotton, Yasine Sakhawoth, Anne-Laure Rollet, Juliette Sireix-Plénet, Lingsam Tea, Sophie Combet, Melissa Sharp, Ingo Hoffmann, Frédéric Nallet, Natalie Malikova

Ion-specific effects in aqueous solutions of polyelectrolytes are addressed here. We focus on ionene cationic chains, featuring simple structure, absence of side-groups and very regular chain charge density. Ion-specific effects in ionene solutions are demonstrated using a series of monovalent (…, Les effets spécifiques des ions dans les solutions aqueuses de polyélectrolytes sont abordés ici. Nous nous concentrons sur les chaînes cationiques de type ionène, qui se caractérisent par une structure simple, l’absence de groupes latéraux et une densité de charge de chaîne très régulière. Les…

What decides the size and composition of clay nano-aggregates in water? Charged polymers and multivalent ions competing in the formation of clay tactoids.

Claire Hotton, Anthony Beauvois, Pierre Levitz, Eric Ferrage, Thomas Bizien, Bruno Demé, Natalie Malikova, Laurent Michot

In this manuscript we address the formation of highly organized clay tactoids intercalated with a charged polymer (ionene) in aqueous environment. We report on an original route to achieve such tactoids by starting with pre-formed clay tactoids, held together by multi-valent inorganic atomic ions,…
