Abstract
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 ∆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.
Highlights
The search for a new class of high performance and high functional organic-inorganic composite ion-exchangers were developed by the incorporation of organic conducting polymers into inorganic precipitates
Heavy metals contamination exists in aqueous waste stream from many industries such as metal plating, mining, tanneries, and painting, car radiator manufacturing, as well as agricultural sources where fertilizers and fungicidal spray were intensively used
The present study shows that polyacrylamide ferric antimonate is an effective adsorbent for the removal of
Summary
The search for a new class of high performance and high functional organic-inorganic composite ion-exchangers were developed by the incorporation of organic conducting polymers into inorganic precipitates (Khan et al, 2003, 2003; Khan andAlam, 2004). The weight loss of polyacrylamide ferric antimonate in the different forms such as H(I), Pb (II), Fe (III), Cd (II), Cu (II) and Zn (II) ions at 1000°C were determined using thermal analysis technique (TG and DTA) to be 34.9, 17.33, 19.81, 21.55, 21.22 and Chemical stability of polyacrylamide ferric antimonate ion exchangers were studied in water, nitric and hydrochloric acid [1, 2, 3, 4, 5 and 6 M], as well as in potassium and sodium hydroxide
