Adsorption of Chromium(VI) on Radiation Grafted N,N-dimethylaminoethylmethacrylate onto Polypropylene, from Aqueous Solutions

Polypropylene (PP) grafted with dimethylaminoethyl- methacrylate (DMAEMA), was prepared by irradiation with a 60Co 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...
