Graft polymerization has been considered as a general method for the modification of the physical and chemical properties of polymeric materials and of particular interest for synthesis of the hydrophilic membrane. In this study, hydrophilic carboxylic acid groups were introduced by radiation-induced grafting of acrylic acid AAc onto non-woven polypropylene fabric NWPP. Different irradiation doses and AAc monomer concentrations were used to optimize grafting yield. Characterization and properties of the prepared graft copolymer were studied by employing X-ray Dif-fraction XRD, Thermogravimetric Analysis TGA, Scanning Electron Microscope SEM , Fourier Transform Infrared Spectrometry FTIR and differential scanning calorimeter DSC. The prepared grafted materials were used for removing some heavy metals ions. The results showed that the non-woven PP grafted with AAc has good affinity toward Cu, Ni and Co.
