Synergistic interplay between D2EHPA and TBP towards the extraction of lithium using hollow fiber supported liquid membrane

Highly selective transport of lithium across a supported liquid membrane

“…Thus, seawater is promising with this SLM system. The permeation coefficients obtained for lithium in this work (P Li up to 5x10 -3 cm.s -1 ) are higher than the permeation oefficients reported in the literature so far for the extraction of lithium [17], [19], [32]. The selectivity for lithium is also very promising, since the permeation ratio of sodium is not higher than 3X10 -4 cm.s -1 .…”

Molecular Insights into Water Clusters Formed in Tributylphosphate–Di-(2-ethylhexyl)phosphoric Acid Extractant Systems from Experiments and Molecular Dynamics Simulations

“…A combination of D2EHPA with tributyl phosphate (TBP) was found to demonstrate high selectivity for extracting lithium from sea bittern over sodium and potassium ions. 6 Separation factor for Li over Na or K ions was found to decrease with increase in the concentration of Na and K ions.…”

Solvent extraction of lithium from simulated shale gas produced water with a bifunctional ionic liquid

“…The distribution ratio values for lithium obtained with Aliquat-336 are negligible, which evidence that this extracting molecule has no affinity for the lithium ion. The distribution ratio values obtained with DEHPA alone are significant but remain low (DLi<0.1), which indicates that DEHPA can coordinate with the lithium ion [32], [19]. However, the acidic form of DEHPA is involved in the formation of dimers in the organic phase (Fig.…”
