Poly(acrylo-amidino diethylene diamine) was synthesized to study the effects of hydrogen bonding to complexes at different pH’s. The polymer was synthesized by coupling diethylene triamine to polyacrylonitrile (PAN) fiber in the presence of the AlCl3·6H2O addition. The adsorption capacity of this polymer was 11.4 meq/g. The ions used for the adsorption test were CrO42-, PO43-, Cu2+, Ni2+, Fe2+ and Ag+. All experiments were confirmed by FT-IR. In the study of anion adsorption, at low pH, only ionic bonds existed, whereas at high pH region, no bonds existed. However, in the middle pH region, both ionic bonds and hydrogen bonds formed between the poly(acrylo-amidino diethylene diamine) and the chromate ion or phosphate ion. When poly(acrylo-amidino diethylene diamine) and metal ions (Cu2+, Ni2+, Fe2+ and Ag+) formed complexes, a hydrogen bonding effect was not observed by FT-IR. |
