The complexes-AOCF-Fe(Ⅲ)was prepared by the reaction of Fe3+ with the fiber containing amidoxime groups(AOCF).This fiber was then used for the adsorption of Reactive Yellow K-6G,with the influences of adsorption temperature,time,pH value,and adsorption Kinetics ware studied.The results show that the optimum conditions of the adsorption are as follows:T=40℃,pH=2.0 and t=2h.The saturated capacity of the dye is 593mg/g;the adsorption action is monolayer and the adsorption kinetics accorded with the character of the second order reaction.
