Copper II Removal from Aqueous Solutions by Adsorption Method: Isothermal, Thermodynamic and Kinetic Studies

Abstract

Study presents the utility of magnetic poly ethyleneglycoldimethacrylate-N-vinyl-2-pyrrolidone [m-p EG- VPN ] microspheres as an adsorbent for copper II ion removal from aqueous solutions. The magnetic polymer microspheres were characterized by elemental analysis, N2 adsorption-desorption isotherm tests, swelling studies, scanning electron microscope SEM and vibrating sample magnetometer VSM . Adsorption studies revealed that the maximum adsorption capacity of m-p EG-VPN microspheres was 270.3 mg/g. Besides, kinetic, isothermal and thermodynamic properties of the adsorption were also investigated.
