Incorporation of a polymer material into an inorganic ion exchanger provides a class of hybrid ion exchangers with a good ion exchange capacity, high stability and high selectivity for heavy metals. We can see these properties in the present study. The kinetic of Fe (III), Pb (II), Cd (II), Cu (II), and Zn (II) ions on polyacrylamide ferric antimonate has been studied. The thermodynamic parameters such as activation energy (Ea), entropy of activation âˆ†S* and diffusion coefficient (Do) have been evaluated and a correlation has been made of these parameters with the ion exchange characteristics of the material.
Key words: Synthesis, polyacrylamide ferric antimonite, adsorption, isotherm, diffusion, heavy metals.
