Brilliant Blue G

In this study, Beta-Cyclodextrin Coated Cobalt Ferrite nanoparticles (CoFe²O₄@BCD NPs) are synthesized and characterized to assess their efficacy in enhancing the adsorption of Coomassie Brilliant Blue dye.The nanoparticles, which is synthesized by coprecipitation method, exhibit an average size of 14 nm and a magnetic saturation of 48.53 A·m₂/kg.Rapid adsorption kinetic is observed with 87 % of the removed dye within the first 3 min while achieving saturation within 5 min corresponding to a maximum adsorption capacity of 175.81 mg/g.The adsorption process conforms to a pseudo-second-order kinetic model (R²=1) and remains stable under varying pH, temperature, and saline/glucose conditions even though minor fluctuations in adsorption capacity are noted.Regeneration tests show that the CoFe₂O₄@BCD NPs retain their performance over five cycles.Cytotoxicity assays on the A549 human alveolar adenocarcinoma cell line confirms their biocompatibility.With their rapid, high-capacity adsorption, magnetic properties, and biocompatibility, CoFe₂O₄@BCD NPs offer significant potential for future water remediation applications.

Given the broad application potential of hypercrosslinked porous polymers (HCPs), recent research has focused on enhancing the sustainability of their synthesis.Current methods still face challenges such as low reaction efficiency and significant chlorinated wastewater.Here, HCPs were efficiently synthesized at room temperature using Lewis or Bronsted-Lewis acidic ILs as dual solvent-catalysts.The water-tolerant reaction requires no inert atm. and yields HCPs with a BET surface area (SBET) of up to 1172 m²·g^-1 and a yield of up to 87% in 1 h.The catalytic efficiency was further enhanced by blending ILs with 1,2-dichloroethane (DCE).Optimized conditions with a specific ILs mass fraction in the solvent yielded HCPs with an SBET of 1386 m²·g^-1and a yield of 88%.The acidic ILs maintained catalytic efficiency over three cycles without producing acidic waste liquidsThe method is scalable to the five-gram level and effectively catalyzes various bis(halomethyl) aromatic cross-linkers.The synthesized HCPs exhibited excellent adsorption performance for organic micropollutants (OMPs), with a maximum adsorption capacity of 1180 mg·g^-1 for Rhodamine B (RhB).This research advances the understanding of HCPs synthesis and proposes a more efficient, environmentally friendly approach using ILs as dual solvent-catalysts, offering a greener pathway for industrial polymer production
