Heavy metal pollution has become one of the most serious environmental problems today due to its difficulty in removal, especially in aquatic environments. The technologies for heavy metal ion removal from aqueous solutions are, chemical treatment, physico-chemical treatment and biological treatment. However, the existing methods are relatively expensive. Therefore, there is an urgency that some environmentally sound and practically feasible technologies or sorbents are needed to be developed. In this study, a modified montmorillonite was used for the removal of Cd2+ ions from aqueous solutions. The influence of various operating parameters on the adsorption process was investigated. The kinetics and equilibrium adsorption of Cd2+ ions from aqueous solutions using the modified montmorillonite were also discussed in detail. The objective of this study is to provide fundamental information on the adsorption of heavy metals from aqueous solution on the modified montmorillonite and to investigate the possible mechanisms.Keywords
