Nonideal H+ adsorption on the chelating fiber can be described adequately by the use of the heterogeneity factor 9 and the parameter beta indicates the geometric factor of effective concentration in this model. The best fits of amines adsorption data were obtained by means of the developed model using two factors. Poly(acrylo-amidino diethylene diamine) was synthesized as a chelating polymer through the coupling of diethylene triamine with polyacrylonitrile fiber in the presence of AlCl3 . 6H(2)O addition. Chromate ion and phosphate ion adsorption data on the synthesized poly(acrylo-amidino diethylene diamine) were obtained. Fourier transform infrared studies of these adsorptions were also performed.
