Ion-Exchange Applications of Newly Synthesized of Aminoacetophenone, Biuret, Formaldehyde Derivative as New Chelating Terpolymer Resin

摘要

A new chelating terpolymer resin (o-AABF) was synthesized through copolymerization of o-amino acetophenone, biuret, formaldehyde in (1:1:3) mol ratio in acidic medium (HC1) by condensation reaction. The synthesized copolymer resin was characterized by UV-visible, FTIR and ~1H NMR techniques. The empirical structure and molecular weight of the resin were analyzed by elemental analysis. Morphological structure of the synthesized resin was studied by scanning electron microscopy. Thermal properties and stability of the resin was determined by DSC and TGA. The intrinsic viscosity and the viscosity average molecular weight were calculated. Selectivity and binding capacity of the terpolymer resin studied by batch equilibrium method toward Ni~(2+) Co~(2+) Cd~(2+) Cu~(2+), Zn~(2+) and Cr~(3+) in different pH and treatment time.
