Acidic surfactant solutions for tributylphosphate removal in nuclear fuel reprocessing plants: A formulation study

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

“…The polyethylene oxide-polypropylene oxide-polyethylene oxide (PEO-PPO-PEO) based nonionic surfactants called Pluronics®, have been the subject of extensive studies in the last few decades because of their rich structural polymorphism [1][2][3][4][5][6][7][8][9][10][11] and a number of industrial applications. [12][13][14][15][16][17][18][19][20][21][22] Unlike conventional ionic and nonionic surfactants, these triblock copolymers exhibit a strong temperature dependence of their surface active properties in an aqueous medium. At low temperature both the PEO and PPO blocks remains soluble in water and the copolymers exist as unimers.…”

“…Pluronics are good solubilizing agent for poorly water soluble substances, 2 due to which they are considered as suitable for applications in the elds like drug delivery, oil extraction etc. [12][13][14][15][16][17][18][19][20][21] Literature reports show that incorporation of such poorly soluble substances into the Pluronic® micelles leads to micellar dehydration and subsequent observations of sphere-torod micellar growth or onset of inter micellar attractive interaction. [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.…”

“…[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.…”

Effect of Different Surfactant on Leaching of Uranium in Sandstone Type Ores with Low Permeability

“…But many sandstone U deposits behave low permeability which is difficult by ISL production. The surfactant, which decreases surface tension with very low concentration, is used increasingly on mining, ores processing and petroleum [6][7][8][9].…”
