Abstract: Degraded chitosan, with highly water-solubility, was obtained by the oxidation of chitosan with H2O2, and then reacted with furfural The final product coordinated with the rare earth ions (RE3+ = Sm3+,Eu3+), which led to the formation of the complexes. The prepared complexes were characterized with Inflated Spectroscopy (IR), Ultra Violet (UV), fluorescence, X-Ray Diffraction (XRD), and Thermogravimetric-Differential Scanning Calorimetry (TG-DSC) measurements.
