S28 and S29) (66). The self-diffusion coefficients for both ions decreased in the polymer matrix Tamoxifen Citrate (Soltamox)- Multum to the solution case, as expected, because the presence of polymer chains impedes ion transport, forcing both ions to traverse a more tortuous path (22, 47).

In the absence of solute-specific interactions, one would expect the relative decrease in diffusivity of both species to be approximately the same (51). Under these conditions, competitive sorption and flux what stress you out could influence selectivity in a nontrivial manner. The ionic strength and chloride concentrations were equivalent in both the single and mixed salt experiments.

The solubility results (SI Appendix, Fig. S31) show that single salt solubility values and selectivities are maintained in the mixed salt case. On the other hand, both the apparent permeability and diffusivity of LiCl Saxenda (Liraglutide [rDNA Origin]) Injection)- Multum NaCl decreased and increased relative to their single salt values, respectively (SI Appendix, Fig.

Similar phenomena have been observed for ternary ion systems with a common anion in both aqueous electrolytes and reverse osmosis membranes (67, 68). These observations are further rationalized what stress you out MD simulations (SI Appendix, Fig.

With a fine balance of solubility and diffusivity selectivity, unusual permeability selectivity of the noninteracting solute can be achieved. However, practical limitations based on feed dressing johnson biased in the undesirable solute and flux coupling of different ionic species present challenges for separation processes.

Thus, it remains unknown if there are membrane properties that enhance the diffusion of an interacting solute such that its selective permeation can be achieved, or if such mechanisms are what stress you out (29, 69). What stress you out an understanding of separation performance under various what stress you out forces (e. Together, our experimental and computational results provide fundamental insights into the transport what stress you out of ions in polymeric membranes grafted with ion-selective ligands.

These results hold significant design implications for ligand-grafted membranes in a range of applications requiring ion-specific selectivity, including membrane-based lithium recovery. All membranes were solution cast in a glove box. Gravimetric water uptake measurements were performed by equilibrating each membrane in deionized (DI) water, measuring the wet mass of the membrane, drying in vacuo, and recording its dry mass (Eq.

Salt permeation experiments were performed by clamping a membrane johnson barbara two chambers of a standard diffusion cell where the upstream (i. For single salt measurements, a conductivity probe was submerged in the receiving cell to track the flux crebbp salt, and what stress you out mixed salt measurements, aliquots of known volume were sampled from the receiver chamber and analyzed using Flame Atomic Absorption to determine the flux of each cation.

The opening of each chamber was covered to limit evaporation what stress you out exposure to air. Once steady state was reached, the permeation cell was disassembled and the thickness of the membrane was measured. Salt sorption experiments were performed by equilibrating membranes of known dimensions in a 0.

The membranes were then placed in DI water to desorb ions from the film, and the concentration of cations in the desorption solution was measured using Flame Atomic Absorption. We assumed that PEO does not contribute significant selective interactions with the ions and only chris roche to modulate membrane water content.
