Trimethylamine functionalized radiation-induced grafted polyamide 6 fibers for p-nitrophenol adsorption

Abstract The method of pre-irradiation grafting was used with the aid of electron beam (EB) accelerator to accomplish the grafting of polyamide 6 fibers (PA6) with glycidyl methacrylate (GMA). The extent to which GMA was grafted on PA6 was found to be markedly influenced by the absorbed dose of radi...
