Abstrak/Abstract The magnetic adsorbent of Fe3O4@SiO2 nanoparticle is modified with an amine group for recovery electroplating industrial waste, which contains Cu2+ ion. The magnetic nanoparticles (MNPs) were prepared by the coprecipitation method under sonication and were coated with SiO2 by acid hydrolysis of sodium citrate under N2 purging. The nanoparticles were prepared by a coating of silica onto the magnetite nanoparticles via controlled hydrolysis of tetraethyl orthosilicate (TEOS). TEM images suggest that the products have a spherical shape with a particle size of about 20 nm in diameter, and the silica-coated magnetite has a core-shell structure. The Cu2+ ion adsorption by magnetic nanoparticles follows the Langmuir isotherm model with a maximum adsorption capacity of 51.04 mg/g at pH 3. The copper ion adsorption by modified MNPs provides easy access to the separation for both the preparation and recovery.
