Cobalt-ferrite (CoFe2O4) and starch-coated CoFe2O4 nanoparticles were prepared by the
mechanochemical method and carefully chosen as adsorbents for Cr(VI) removal from
wastewater. The kinetic study, adsorption isotherms and influence of pH, contact time and
interfering ions were investigated to have deeper insight into adsorbent quality. UV/Vis
spectroscopy confirmed that the dominant adsorption mechanism is the electrostatic
attraction at lower pH values. The study showed there was no significant change in
adsorption efficiency for starch-coated nanoparticles. However, starch as a natural and
biocompatible compound can enhance nanoparticles water dispersibility. The advantage of
such materials is that saturation time does not exceed 20 minutes. Therefore, the as-prepared
and starch-coated CoFe2O4 presents very efficient material for application in the field of
water remediation.
