Abstract:
The deacetylations(DD) of Chitosan and chitooligosaccharide(COS) were titrated by an acidbase method. After Sephadex chromatography purification, the degree of polymerization(DP) and DD were obtained by MALDI-FT-MS. It was found that Chitosan has high an adsorption of the radionuclide Uranium. Chitosan showed high adsorption of radionuclide uranium even with the presence of large amount of Cu2+ ions. The adsorption efficiency is above 96%. This shows that Chitosan has a great potential for the renoval of both heavy metals and radionuclides.
