Abstract
The adsorption behavior of Hg(II), Pb(II), and Cd(II) on Duolite C-433 synthetic resin has been determined at different temperatures by batch process. The various thermodynamic parameters, such as equilibrium constant (
K
0), free energy (Δ
G
0), entropy (Δ
S
0), and enthalpy (Δ
H
0), have been calculated in order to predict the nature of sorption.
