Micellar solubilization of tributylphosphate in aqueous solutions of Pluronic block copolymers

TBP induced double cloud point in aqueous EO13PO30EO13 solutions: investigating the evolution of associated micellar characteristics as a function of temperature

“…[23][24][25][26] Recent studies show that aqueous solutions of pluronic P123, P84, L44 and L64 can solubilize tributyl phosphate (TBP) and thus could be considered as potential material for removal of TBP from nuclear fuel reprocessing plants. 19,[27][28][29][30] It has also been shown that its solubilization in these systems leads to a decrease in their CP and in addition induction of a second CP at low temperature, called solubilization minimum temperature (SMT). [27][28][29][30] Existence of double cloud point is known to occur in aqueous solutions of Pluronic L62 and L92 (ref.…”

Solubilization of Aromatic Hydrocarbons in Ethylene Oxide‐Propylene Oxide Triblock Micelles: Location of Solubilizate and its Effect on Micelle Size from 2D NMR and Scattering Techniques

“…Cosgrove and coworkers [29] have recently studied solubilization of two model adjuvants, benzyl benzoate and benzyl alcohol, in TBCP micelles by SANS and NMR and observed that micellization was promoted in the presence of additives. The solubilization of tributyl phosphate (TBP), a polar oil in TBCP micelles has been investigated by 1 H-NMR spectroscopy [30]. The kinetics studies on solubilization of benzene in triblock copolymers solutions show that the rate of benzene solubilization by copolymer micelles is significantly fast and increases with increasing temperature [31].…”

Microemulsions - A Brief Introduction

“…Using 2H NMR studies, it was indicated that five water molecule are tightly bound to each CTAB molecule. The chemical shifts and T1 relaxation time data obtained by 1H NMR measurements were used to investigate the microemulsion properties and structure (Waysbort et al, 1997, Bastogne et al, 1999, Kataoka et al, 2007, Causse et al, 2006.…”
