Ionic liquid covered iron-oxide magnetic nanoparticles decorated zeolite nanocomposite for excellent catalytic reduction and degradation of environmental toxic organic pollutants and dyes

Hydrophobic ionic liquid (IL)-based magnetic adsorbents: the way forward to remediate water pollution

“…Notably, the catalyst, easily recoverable via an external magnet, demonstrated outstanding recyclability with minimal loss of activity, highlighting its promising potential for environmentally friendly and cost-effective applications in environmental protection. 57 A comparison between different NPs and ILs at a constant pH of 6, contact time of 100 min, metal concentration of 40 ppm, NP dose of 170 mg and temperature of 60 °C was made. Maximum Cr( vi ) metal removal was observed with FeO-IL2 with a maximum adsorption of 77.21% as shown in Fig.…”

Column adsorption of biological oxygen demand, chemical oxygen demand and total organic carbon from wastewater by magnetite nanoparticles-zeolite A composite

“…Among them, magnetite-zeolite composite has been prepared previously to treat wastewater, for instance, Du et al [ 36 ] reported the removal of cadmium ions in a batch adsorption system using modified zeolite-supported nanoscale zero-valent iron composites. In another study, iron-oxide nanoparticles decorated zeolite nanocomposite were covered with ionic liquid for the catalytic reduction and degradation of 2-nitroaniline, 3-nitroaniline, 4-nitroaniline, Nitrophenyl diamine and dyes (Methylene blue and Allura red) [ 43 ]. Also, NaA zeolite-coated nanoparticles (NZCMNs) were prepared and investigated for the removal of Pb (II) and Cu (II) ions from aqueous solutions [ 44 ].…”

Novel Magnetic Bimetallic AuCu Catalyst for Reduction of Nitroarenes and Degradation of Organic Dyes

“…13 In addition, some portions of these dyes are released in sewage producing harmful effects to humans, animals, and all living organisms. 14 Adsorption, coagulation, oxidation, and membrane separation are some of the practical methods for removing dyes from industrial e uents. 15 Tetracycline (TC) is other damaging contaminant, which is broadly utilized as antibiotic in the bacterial infections treatment, agriculture, and sh farming.…”
