Abstract

It has been studied the correlation between cavity fraction of Cu2+ ionic imprinting and concentration of H+ ion in solution media upon adsorbent ability of amino-silica hybrid of Cu2+ ionic imprinting (Cu(II)-IIP) in adsorbing Cu2+ ions in solution. In order to identify the active sites playing a role upon Cu2+ ion adsorption, identification of functional groups, surface morphology, element compositions, surface area, volume, and porous diameter of adsorbent were investigated in this experiment. Adsorption process was performed using batch method with interacting Cu(II)-IIP adsorbent with each cavity fraction of ionic imprinting of Cu(II)-IIP-1; Cu(II)-IIP-2; Cu(II)-IIP-3; and Cu(II)-IIP-4 of 97.69; 98.75; 97.87; 96.89 % in solution media with each concentration of H+ ion of 0.5; 1.0; 1.5; 2.5; 5.0 mmol L-1, respectively. The adsorption data obtained showed that Cu(II)-IIP with different ionic imprinting fractions gave relatively similar adsorption models, the higher the concentration of H+ ion in solution media, the lower the concentration of Cu2+ ion adsorbed on the Cu(II)-IIP adsorbent. From the evaluation results of the adsorption kinetic and adsorption isotherm parameters show that the values of the adsorption rate and capacity of ionic imprinted materials on Cu(II)-IIP-1; Cu(II)-IIP-2; Cu(II)-IIP-3; and Cu(II)-IIP-4 are bigger than non-imprinted polymer (NIP). Keywords: imprinted ionic, adsorption, aminosilica hybrid, adsorption active site.
