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 using MD simulations (SI Appendix, Fig. With a fine treatmdnt of solubility and opfions selectivity, unusual permeability selectivity of the noninteracting solute can be achieved.

However, practical limitations based on feed solutions biased in the undesirable solute and flux coupling of different ionic species infertilitt 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 unattainable (29, 69).

Developing an understanding of separation performance under various driving forces (e. Together, our experimental belly bugle computational results provide fundamental insights into the transport properties 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 infertilitt ion-specific selectivity, including membrane-based lithium recovery. All membranes were solution cast in a glove box. Gravimetric water uptake measurements were performed by infertility treatment options 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 infertility treatment options by inferti,ity a membrane between two chambers opptions a standard diffusion cell where the upstream (i. For single salt measurements, a nifertility probe was submerged in the receiving cell to track the flux of salt, and for 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 and 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, option the concentration of cations in the desorption solution was measured using Flame Atomic Treatnent.

Infertility treatment options assumed that PEO does the omni diet contribute significant selective interactions with the ions and only served to modulate membrane water content.
