Poly(acryloamidino ethyleneamine) and poly(acryloamidino diethylenediamine) are synthesized as chelating polymers, and Cu(OH)(2) crystal growth with the change of pH in an aqueous solution are observed using field-emission scanning electron microscopy. It is shown that the shapes of grown Cu(II) crystals on the chelating polymers depend on their alkyl amine numbers. The best fits of the isotherm data for Cu(2+) adsorption and Cu(OH)(2) crystal growth on the chelating polymers are obtained by means of our developed model. (C) 2011 American Institute of Physics.
