Adsorption studies for removal of trace copper metal ions from aqueous samples using magnetic nanoparticles

Fe3O4 magnetic nanoparticles (MNPs) synthesized in-housed using co-precipitation method was assessed for the treatment of synthetic aqueous solutions contaminated by Cu(II) ions. Experimental results showed that at 25ºC, the optimum value for Cu(II) removal was pH 6.0 and an adsorbent dose of 60.0 m...
