Direct lithium extraction from unconventional resources requires the development of effective adsorbents. Crown ether-containing materials have been reported as promising structures in terms selectivity, but data on adsorption real, highly saline brines are scarce. ether-grafted graphene oxides were synthesized using 2-hydroxymethyl-12-crown-4, hydroxy-dibenzo-14-crown-4 and epichlorohydrin a source anchoring groups. The obtained carbonaceous used to prepare chitosan–polyvinyl alcohol composites. prepared (and intermediate products) characterized FTIR, XRD, Raman spectroscopy SEM-EDS methods. Adsorption tests performed pure diluted LiCl solution ([Li] = 200 mg/kg) well oilfield brine ≈ 220 mg/kg), distribution coefficients (Kd) determined. results show that Kd was range 0.9–75.6, while it 0.2–2.3. study indicates high affinity for is mostly associated with non-selective interaction ions oxide matrix (COOH groups). It also shown application dibenzo-14-crown-4 moiety modification groups increases composite material compared an analogous containing 12-crown-4-ether

Correlations between conditions of the polyaniline (PANI) interlayer formation on surface a polysulfone (PSF) porous membrane substrate and structure performance thin-film composite (TFC) membranes for nanofiltration with polyamide (PA) selective layer prepared via interfacial polymerization (IP) were studied. It was shown that application PANI significantly enhanced hydrophilicity (the water contact angle decreased from 55 ± 2° down to 26–49 2°), pore size porosity, increased roughness PSF/PANI substrates due bigger globules, which affect PA TFC IP. intermediate yielded thinner layer, decline in roughness, an increase declined 28 <10°) crosslinking degree NF membranes. The developed approach allows us enhance permeation up 45–64 L·m−2·h−1 at ΔP = 0.5 MPa improve selectivity (rejection coefficient MgSO4—>99.99%; LiCl—5–25%; sulfadimetoxine—80–95%) also ensure long-term operational stability interlayer. Moreover, Mg2+/Li+ separation factor values found 37 58 PANI-modified compared 9 8 reference NF-PSF
