| Abstract | ||
| Grafting of wastes polypropylene taken from sack with some active functional groups like maleic anhydride, N- phenylmaleamic acid, N( o-chloro-phenyl) maleamic acid, N( 2,6-diethyphenyl) maleamic acid and N(3-chloro-4-methylphenyl) maleamic acid were accomplished via free radical polymerization. The grafted polymers were examined as an ion exchanger toward Cu+2, Zn+2 and Cd+2 ions from their aqueous solutions. The initial concentrations of metal ion solution, pH of the extraction medium and treatment time were studied as a factors influence the efficiency of extraction. The r esults were constructed with some isotherm models (Langmuir, Frendlich and Dubiuin-Radushkevish models). The langmuir and Dubini-Radushkevish isotherm are the more suitable models to describe the results than Frendlich model. | ||
