Abstract

In this research, it has been evaluated concentration effect of Cd2+ ion used as Cd2+ionic imprinted on synthesis of ionic imprinted aminosilica hybrid (Cd(II)-IIP) adsorbent upon adsorption rate and capacity of target ion (Cd2+ ) in solution. The results of the ionic imprinting (as active sites of Cd2+ ion) obtained were prepared from different concentrations of Cd2+ ion producing different ionic imprinted cavity fraction. The concentrations of Cd2+ ion used as the ionic imprinting were 0.05, 0.10, and 0.15 mol L- 1 resulting the ionic imprinted cavity fraction for each 97.89 ± 0.20 (Cd(II)-IIPa), 98.49 ± 0.10 (Cd(II)-IIPb), and 95.82 ± 0.25 % (Cd(II)-IIPc),respectively. From the adsorption data obtained, they shows that initial concentration differences of imprinted ion produce different adsorption models of Cd2+ ion. The bigger the Cd2+ ionic imprinting fraction, the higher the adsorption rate (k ) and capacity (q) of ion on adsorbent. Keywords: imprinted ionic; adsorption; aminosilica hybrid; adsorption active site
