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