•Fe3O4-DES nanoparticles were made in choline chloride–urea deep eutectic solvent.•Fe3O4-DES nanoparticles (ca. 10.5 nm) are of soft magnetic character.•Fe3O4-DES/EDTA magnetic nano-adsorbent has high Cu2+ adsorption capacity.Fe3O4 nanoparticles have been widely explored in magnetic separation, and are usually made in water or organic solvents. In this work, spherical Fe3O4-DES magnetic nanoparticles of ca. 10.5 nm were prepared by co-precipitating Fe3+ and Fe2+ ions in ionic solvent comprising choline chloride/urea deep eutectic mixture for the first time. Upon surface modification by ethylenediamine tetraacetate (EDTA), the Fe3O4-DES/EDTA magnetic nano-adsorbent has significantly improved Cu2+ adsorption capacity than Fe3O4-DW/EDTA (28 vs. 21 mg/gFe3O4), where Fe3O4-DW is synthesized in water under otherwise identical conditions.Spherical Fe3O4 magnetic nanoparticles (Fe3O4-DES) with average particle size of ca. 10.5 nm were prepared by co-precipitating Fe3+ and Fe2+ ions in ionic solvent comprising choline chloride–urea deep eutectic mixture for the first time. Compared to Fe3O4 made in water, Fe3O4-DES nanoparticles show significantly improved adsorption capacity of Cu2+ after surface modification with EDTA (28.0 vs. 21.0 mg/gFe3O4).
