Polypropylene amidoxime (PPAO) chelate fibre is synthesized by pre-irradiation graft polymerization and amidoximation. Influences of irradiation atmosphere, type of solvent, solution volume and monomer concentration on degree of grafting were studied. Experimental results show that higher degree of grafting could be achieved by irradiating the PPAO finres in air at 70ºC and grafting the samples in a monomer solution of 30% acrylonitrile in concentration solved in water or 10% methol aqueous solution. Adsorption of Pb(Ⅱ) by the grafted PPAO was tested, and Pb(Ⅱ) adsorption capacity of 0. 362 mg per gram of the fibre (dry weight) could be obtained.
