Abstract

Adsorption process on Cd2+ionic  imprinted mercapto-silica hybrid material  (Cd(II)-IIP HMS) has been carried out with studying an adsorption competition between ion H+ and Cd2+ ion upon active sites of Cd(II)-IIP HMS material.  Characterization of surface material was based on specific surface area, total volume, and porous diameter.  Cd(II)-IIP HMS material with template ionic concentration of each 0.107; 0.214; 0.429; 0.658 mmol g-1 shows  that adsorption model  is relatively similar, the higher of H+ ion competed,  the  lower of adsorption capacity of Cd(II)-IIP HMS material upon Cd2+ ion.  Keywords: adsorption, active site, mercapto-silica hybrid, ionic imprinted

Abstract

Chemical stability of Cd(II) and Cu(II) ionic imprinted amino-silica (HAS) material of (i-Cd-HAS and i-Cu-HAS) derived from silica modification with active compound (3-aminopropyl)-trimethoxysilane (3-APTMS) has been studied in solution media.  Stability test was performed with HNO3 0.1 M (pH 1.35) to investigate material stability at low pH condition, acetat buffer at pH 5.22 for adsorption process optimum pH condition, and in the water (pH 9.34) for base condition.  Material characteristics were carried out with infrared spectrophotometer (IR) and atomic absorption spectrophotometer (AAS).  At interaction time of 4 days in acid and neutral condition, i-Cd-HAS is more stable than i-Cu-HAS with % Si left in material 95.89 % (acid media), 43.82 % (close to neutral), and 9.39 % (base media).Keywords: chemical stability, amino-silica hybrid, ionic imprinting technique.
