Polypropylene (PP) grafted with dimethylaminoethyl- methacrylate (DMAEMA), was prepared by irradiation with a 60 Co γ source. The obtained PP-g-DMAEMA was used to study the Cr(VI) ion adsorption as a function of contact time, initial pH, initial concen- tration of metal ion and temperature. Chromium adsorption data on PP-g-DMAEMA at various initial concentration fit well the Freundlich and Langmuir isotherms. The maximum adsorption capacity (amax) was found to be 0.3103 × 0 -4 mol g -1 . The thermodynamic parameters ΔH 0 , ΔG 0 and ΔS 0 were estimated showing the adsorption process to
