Abstract : The preparation of amino-functionalized silica gel adsorbents (APTS-Cr(III)-Si and APTS-Fe(III)-Si) for
selective solid-phase extraction of Cr(III) and Fe(III), respectively, from aqueous solutions. The adsorbent materials were
prepared by a surface imprinting technique using 3-aminopropyltrimethoxysilane as the surface modifying ligand. The
effects of solution pH, sorption time, temperature, and initial metal ion concentration upon adsorption characteristics were
investigated. The adsorption isotherms for Langmuir and Freundlich evaluated the adsorption processes. By optimizing the
parameters, the synthesized materials could be used successfully for selective removal of trivalent cations from a mixture of
cations in dilute aqueous solution.
