[Syntheses and spectral characterization of low-molecular-weight chitosan-Ce(III) complexes].
The low-molecular-weight chitosan-Ce(III) complexes were synthesized at pH value 1-2 and characterized by UV spectrum, fluorescence spectrum, FTIR spectrum and 1H NMR spectrum. Its coordination mechanism was also investigated. The results showed that Ce(III) was coordinated with -OH group instead of -NH2 group of low-molecular-weight chitosan.
