Removal of Neodymium from Aqueous Solutions Using a New Fe-modified Nanoporous Adsorbent of Fe-MCM-41

In our study a new fe-modified nano porous of mcm-41 was synthezied hydrothermally with cetyltrimethylammoniumbromide (c_16tab) as surfactant and charactrizied using xrd, sem, ft-ir and bet. this work reports the adsorption of neodymium from aqueous solution onto fe-mcm-41.100 ml of stock solution of neodymium was prepared.various factors such as ph,the amount of adsorbent were considered. the optimium conditions obtained were: ph value= 5-8,the amount of fe-mcm-41=0.0025gr.the langmuir, freundlich, temkin and dubinin-rudeshkuvich models have been applied and the equilibrium adsorption was found fit the freundlich isotherm model(r^2= 0.98). the removal amount of adsorbed neodymium was obtained 97% and charactrizied by inductivity coupled optical emission spectroscopy (icp-oes).
