By utilizing the reaction between -NCO group of ICPES and -NH2 group of 2-picolylamine in acetonitrile, the chelating ligand, 2-(ureylenemethyl)pyridine, has been successfully immobilized over MCM-41 (UMP-MCM-41) without destroying the mesoporous structure. The synthesized materials show very good mesoporosity and long range order. The ability of removing chromium from water and artificial seawater by using the UMP-MCM-41 mesoporous material was explored. The synthesized material showed good adsorption ability for Cr(III) ions from water and artificial seawater with selectivity of 36 and 64%, respectively, in the presence of interfering metal ions such as Zn(II), Cd(II), Co(II), and Cu(II). In order to disclose the adsorption ability of the material from single metal ion solution for Cr(III) ion, factors such as effect of pH, stirring time, initial ion concentration and presence of ethanol in adsorption medium were also explored. Further the experiments revealed that the UMP-MCM-41 is giving maximum adsorption at pH 6. The adsorption equilibrium has been attained within 5h with 84% adsorption. Moreover, the presence of ethanol in the adsorption medium enhances the amount of adsorption.
