| Abstract | ||||
| In the present study, the adsorption of Cd(II) ions onto magnetic glycine modified crosslinked chitosan (MGMCR) resin has been investigated. Batch experiments were performed to study the effect of some parameters such as the initial Cd(II) concentration, pH value of the solution, adsorbent dose and the contact time on the adsorption process. The optimal pH for the adsorption of Cd(II) was found to be at 5 and the equilibrium was accomplished within 120 minutes. The result obtained from equilibrium adsorption studies are fitted in Langmuir and Freundlich adsorption models and the data was found to agree well with the Langmuir model. The maximum uptake was found to be 172 mg g-1 at 25 0C at pH 5. | ||||
