Abstract

The sorption efficiency of superparamagnetic nano iron oxide loaded Polyvinyl Alcohol-Alginate (PVA-A) was investigated for the removal of Cu2+ ions from aqueous solution. Various effects i.e. adsorbent dose, contact time, pH, initial metal ion concentration and temperature were studied. The PVA-A microspheres were magnetized insitu and the size and structure of magnetic nano particles were characterized by XRD, FTIR and TEM analysis. The equilibrium experimental results were analyzed in terms of Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherms to obtain the appropriate model and found that all the isotherms well represented the measured sorption data for Cu2+ and various static parameters were evaluated showing the sorption to be feasible, spontaneous and exothermic in nature. The superparamagnetic PVA-A microspheres have been found to be the efficient adsorbent for removal of toxic Cu2+ ions from industrial wastewater (>99% removal) and could be regenerated efficiently (>98%) and used repeatedly for further experiments.
