Copper ion adsorption characteristics of supermagnetic iron oxide nanocomposite hydrogel based on graft copolymerization of poly((2-dimethylamino)ethyl methacrylate) onto salep

In this research, adsorption properties of the supermagnetic iron oxide nanocomposite hydrogel (SION) for Cu (II) ion removal from aqueous solutions were investigated. At first, SION was prepared using simultaneous in situ formation of iron oxide nanoparticles (IONs) and three-dimensional cross-linked polymer networks based on graft copolymerization of poly((2-dimethylamino)ethyl methacrylate) (PDMA) onto salep (PDMA-g-salep). The prepared SION–PDMA-g-salep hydrogel was systematically characterized by Fourier transforminfrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and vibrating sample magnetometer (VSM). After that, the effects of the contact time and initial Cu (II) solution concentration on adsorption onto obtained SION–PDMA-g-salep hydrogel are comprehensively investigated
