The elimination of small and potentially toxic boron species in water is always a significant challenge for conventional membrane technologies. In this study, facile intercalation functionalization β-cyclodextrin (CD) onto layered double hydroxides (LDHs) have resulted the formation accessible hydroxyl functional groups anions that exhibit strong sorption with boron. Through meticulous molecular design optimization, modified LDH possessing maximum adsorption capacity 96.1 mg g-1 was employed to fabricate polyamide-based thin-film nanocomposite (TFN) loading 0.10 wt.%. This resultant displayed high salt rejection permeance 99.4 % 2.68 LMH bar-1 brackish water, respectively, which can be attributed increased interlayer spacing 1.67 nm thinner selective layer. innovative TFN also achieved 82.3 against containing 2,000 L-1 NaCl 15 B at pH 8. pioneering study provides valuable insights into reverse osmosis (BWRO) membranes, through synergistic use macrocyclic molecules inorganic nanomaterials, could revolutionize reuse removal applications.

Tailoring boron-polysaccharide interactions is an important strategy for developing functional soft materials such as hydrogels, fire retardants, and sorbents environmental remediation, example, using lignocellulosic biomass. For applications to be realized, it paramount understand the adsorption kinetics of borate anions on cellulose their local structures. Here, kinetic aspects boron by microcrystalline cellulose, lignin, polymeric resin are investigated compared. Borate interact with vicinal diols in glucopyranoside moieties yield chemisorbed chelate complexes. In contrast technical lignin contains fewer cis-vicinal diols, does not have a tendency form complexes upon treatment aqueous boric acid solution. The formation stability these strongly depend nanoscale structures, well reaction conditions pH concentration sorbate sorbent. Specifically, insights into distinct sites were obtained solid-state one-dimensional (1D) 11B magic-angle spinning NMR structures intermolecular vicinities elucidated analyzing two-dimensional (2D) 1H-13C 11B-1H heteronuclear correlation spectra. total capacity estimated 1.3-3.0 mg range per gram sorbent, which lower than polystyrene-based resin, ∼17.2 Amberlite IRA 743. Our study demonstrates that backbone side chain flexibility polyol groups play significant role determining thermodynamic complexes, yielding different capabilities polymers.
