| Abstract | ||
| THE POSSIBILITY to reduce the levels of heavy metals from ……aqueous waste solutions by using polyacrylamide ferric antimonate ion-exchangers has been investigated in this study. These composite ion exchangers have high chemical stability and high loading capacity. The materials were characterized using X-ray diffraction analysis, infrared spectroscopy and thermogravemetric and differential thermal analysis. The distribution coefficients and separation factors of prepared materials were calculated for Fe (III), Pb (II), Cd (II), Cu (II), and Zn (II) ions. The samples prepared show high chemical stability in water, nitric and hydrochloric acids, as well as in potassium and sodium hydroxides. All these results support the suitability of the prepared material for removals of heavy metals from aqueous waste solutions. | ||
