Tetraethylenepentamine chelating fiber (TEPACF) has been successfully prepared after acylation and amination of propylene fiber grafted with styreneylbenzene(PP-g-ST). The reaction conditions of acylation and amination are optimized. The synthesis technology of TEPACF is suitable for industrialized production. SEM, photoelectron spectroscopy, IR, TG, XRD and mechanical strength test are used to investigate the structure and properties of TEPACF. The result of adsorption performance test shows that the best adsorption capacity of In(III) on TEPACF is 1.53 mmol·g^-1, and that TEPACF has good adsorption selectivity to In(III).
