Incorporation of a polymermaterial 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 this proberties 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 by applying the Nernest-plank equation. The rate of exchange is controlled by particle diffusion mechanism. The physical thermodynamic parameters such as activation energy and entropy of activation have been evaluated and compared with other inorganic and organic exchangers. The Langmuir and Freundlich models have been applied to the adsorption isotherm and different constants were generated.
