摘要: Abstract Cotton-cellulose was functionalized using gamma-irradiation-induced grafting of glycidyl methacrylate (GMA) to obtain a hydrophobic cellulose derivative with epoxy groups suitable for further chemical modification. Two techniques were applied. In pre-irradiation (PIG) irradiated in air and then immersed GMA monomer solution, whereas simultaneous (SG) an inert atmosphere the presence monomer. PIG led more homogeneous fiber surface, while SG resulted higher yield but showed clear indications some GMA-homopolymerization. Effects reaction parameters (grafting method, absorbed dose, concentration, solvent composition) evaluated by SEM, gravimetry yield) FTIR spectroscopy. Water uptake decreased adsorption pesticide molecule increased upon grafting. The enhanced β-cyclodextrin immobilization during SG. This method can be applied produce adsorbents from based agricultural wastes.
