A bifunctional cotton fabric waste bearing N + (CH 2 CH 3 ) 3 and COOH groups was prepared by radiation induced graft polymerization of glycidyl methacrylate and methacrylic acid using gamma irradiation and subsequent chemical modification of the grafted cotton fabric with triethylamine. Factors affecting the grafting of cotton fabric such as radiation dose and comonomer composition were investigated. The adsorbent was characterized by Fourier transform infrared spectroscopy and scanning electron microscope. Functional groups were tested for its potential application in the removal of cobalt (Co 2+ ) and nitrate (NO 3 − ) from aqueous solutions. Batch experiments were performed to evaluate the adsorption efficiency of the modified grafted cellulose (MGC) towards the cation and the anion. The adsorption capacity for Co 2+ at pH 3 and pH 5 was 36.0 and 38.5 mg/g, respectively, whereas that of nitrate was 11 mg/g at pH 4.5. The adsorption process of Co 2+ and nitrate obeys both Freundlich and Langmuir isotherm models and followed Pseudosecond order kinetics. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
