Acrylonitrile is grafted onto polyethylene non-woven fabric and the amidoxime groups are introduced onto the non-woven fabric by the reaction of nitrile groups with hydroxylamine hydrochloride. The degree of grafting (DG) and the conversion of amidoximation are measured by gravimetric method and the kinetics is studied. The existence of the amidoxime groups is proven by Fourier transform infrared (FT-IR) spectroscopy analysis. Adsorption results show that the absorbent can extract uranyl carbonate ions when the concentration is lower than 3 ppb.
