ACS OMEGA 2022; 7:19743-19753.

Abstract
Sevelamer hydrochloride (SH), originally developed as an oral pharmaceutical for controlling blood phosphate levels, is a polyallylamine resin that could be used in water treatments. Although it binds phosphates effectively, its adsorption capacity suffers from a significant loss at high pH. Here, we modify SH with lanthanum oxalate to improve its phosphate adsorption in alkaline environments. With less than 6.00 wt% in La content, the composite adsorbent (SH-1C-1La) exhibits an adsorption capacity of 109.3 mg P g-1 at pH 8.0 and 100.2 mg P g-1 at pH 10.0, demonstrating significant enhancement from the original SH (86.3 mg P g-1 at pH 8.0 and 69.4 mg P g-1 at pH 10.0). Besides its high adsorption capacity and rapid adsorption kinetics, SH-1C-1La is capable of maintaining more than 78% of its capacity after four regeneration cycles, showing good durability in long-term applications. Zeta-potential measurements and XPS analysis reveal that the lanthanum oxalate species increase the surface potential to enhance the electrostatic adsorption while introducing chemical binding sites for phosphate ions. Both factors lead to the improved adsorption properties. The modification by lanthanum oxalate species might provide a new alternative for improving the phosphate adsorption properties of anion-exchange resins.

Structural Regulation of Magnetic Polymer Microsphere@Ionic Liquids with an Intermediate Protective Layer and Application as Core-Shell-Shell Catalysts with High Stability and Activity.

Abstract
A novel ionic liquid immobilized on a magnetic polymer microsphere catalyst is reported in this paper. The obtained core-shell-shell catalyst consisted of magnetic nanoparticles (MNPs) as the core, catalytic inert St-co-DVB as the intermediate protective layer, and cross-linked polyaryl imidazole ionic liquids as the active catalytic layer located at the outermost [Im[OH]/MNPs@P(St-DVB)@P(VBC-DVB)]. This catalyst exhibited a high ion-exchange rate (64.65%), high saturation magnetic strength, and excellent acid and alkali corrosion resistance. In the catalyzed Knoevenagel condensation of benzaldehyde and ethyl cyanoacetate, the conversion of benzaldehyde maintained at 92.1% during six times reuse. Optimizing the materials of the protective layer and regulating the thickness of the inert protective layer decreased the corrosion ratio of MNPs in acidic media from 44.82 to 0.44%. Adjusting the thickness of the catalytic layer realized excellent catalytic activity (97%) and high magnetic response performance. In summary, introducing an inert protective layer to the structure of ionic liquids immobilized on the magnetic polymer microsphere catalyst, regulating its thickness, and optimizing its structure achieved a catalyst with high activity, excellent stability, and easy magnetic separation.

Abstract
:
The supported ionic liquids have shown immense potential for numerous applications
in catalysis and separation science. In the present review, the remarkable contribution
of supported ionic liquids has been highlighted. The main emphasis has been laid on
describing the facile separation of gas from binary gas mixtures owing to the capability of
selective transport of permeable gases across supported membranes and removal of environmentally
hazard sulfur compounds from fuels. The catalytic action of supported ionic
liquids has been discussed in other applications such as biodiesel (biofuel) synthesis by
transesterification/esterification processes, waste CO2 fixation into advantageous cyclic
carbonates, and various chemical transformations in organic green synthesis. This review
enclosed a maximum of the published data of the last ten years and also recently accomplished
work concerning applications in various research areas like separation sciences, chemical transformations
in organic green synthesis, biofuel synthesis, waste CO2 fixation, and purification of fuels by desulfurization.
