Abstract
Preparation and properties of chitosan modified with heterocycles in absence or presence of gluteraldehyde
as a cross linker is described. New modified chitosan–heterocyclic hydrogels were prepared from
chitosan and heterocyclic compounds such as N,N0-biisomaleimide, N,N0-biisophthalimide, and N,
N0-phthalimidomaleimide via a crosslinking reaction. The new hydrogels chemical structure was characterized
by spectral analysis (IR), X-ray diffraction, thermal gravimetric analysis (TGA), solubility, and
swellability in water and different organic solvents. Evaluation of the efficiency of the new hydrogels
to uptake copper and cobalt ions from aqueous systems was carried out and promising results were
obtained.
