Abstract: In this study a Nd(III) ion imprinted mercapto-functionalized nano alumina sorbent was synthesized via a surface imprinting technique as selective adsorbent for removal of Nd(III) ion from aqueous sample. The effects of different variables such as solution pH, sorption time, adsorbent dosage and initial metal ion concentration upon adsorption characteristics were investigated.The equilibrium data obtained from Nd(III) ions sorption capacity onto the adsorbent were fitted to Langmuir, Freundlich, Temkine and Dobenian-Radushkevich isotherms. The Results revealed that the adsorption process obeyed the Langmuir model and the maximum monolayer capacity (q ) and the Langmuir constant (K ) (were calculated from the max L Langmuir model as 416.7 mg g-1 and 0.273 L mg-1, respectively. Kinetic studies indicated the adsorption process followed a pseudo-second-order model. After optimization the parameters, the synthesized sorbent can be utilizedsuccessfully for selective removal of Nd(III) ions from variouscations in dilute aqueous solution.
