Abstract

A new chelating fiber, poly(acrylo-amidino diethylenediamine, was synthesized based on polyacrylonitrile fibers in diethylenetriamine with the aid of AlCl3. Complex formation with CrO4 2 was strongly pH dependent as complexes formed only in the presence of NH3 + and NH2 +. In the medium pH region, both ionic and hydrogen bonds were formed between poly(acrylo-amidino diethylenediamine) and the chromate ion, as was confirmed by means of FT-IR spectroscopy.
