摘要：

An intramolecular water soluble chitosan-Fe(III) complex was prepared by mixing together chitosan powder with a 1.5 m FeCl2 solution at 30-degrees-C over 24 h in heterogeneous phase followed by extraction with acetone of the excess ferric chloride. The complex was characterized by IR and far IR spectrometry, differential thermal analysis, differential scanning calorimetry, mass spectrometry and Mossbauer spectroscopy. It was concluded that the ferric ion is coordinated with two chitosan residues, three molecules of water and one chloride ion.
