Abstract
In this research, it has been evaluated concentration effect of Cd2+ ion used as the Cd2+ ionic imprinted on synthesis of the Cd2+ ionic imprinted amino-silica hybrid (Cd(II)-IIP) adsorbent to adsorption rate and capacity of the target ion (Cd2+) in solution. The results of the ionic imprinting (as active sites of Cd2+ ion) obtained were prepared from different concentrations of the Cd2+ ion producing the 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 (Cd(II)-IIPa), 98.49 (Cd(II)-IIPb), and 95.82 % (Cd(II)-IIPc), respectively. From the adsorption data obtained, they show that initial concentration differences of the imprinted Cd2+ ion produce different adsorption models of the Cd2+ ion. The bigger the Cd2+ ionic imprinting fraction, the higher the adsorption rate (k1) and capacity (q) of Cd2+ ion on the adsorbent.
