Removal of Ni(II) ions from aqueous solutions using fixed-bed ion exchange column technique

Ion exchange represents an efficient technique for removing of heavy metals from wastewater effluents. Limited number of studies focuses on fixed bed performance for metal removal. In this study, the removal of Ni2+ from synthetic wastewater using a strong acidic cation exchange resin in a fixed b...
