Abstract
In this paper a study was carried out to estimate the ability of Bentonite clay as a new adsorbent surface for removal and adsorption of Cadmium ion from aqueous solutions . The effect of contact time was evaluted and found that the removal process of Cadmium Ion by Bentoniite surafce was reached complete equilibrium at 60 min .The maximum removal or adsorption of Cadmium ion by Bentonite adsorbent were found 87.2% at 40 min . The kinetic results were well fitted to lagergren pseudo – second order models . This behavior was discussed depending on the chemical structure of Cadmium ion and Bentonite surface area. The intraparticle difusion model was also used to studied the kinetics and mechanisms of Cadmium Ion removal . Results model plays a significant role in the adsorption mechanism
