Structures of Chitosan and Chitooligosaccharide and Their Adsorption toward Radionuclide Uranium
Abstract:
The deacetylations(DD) of chitosan and chitooligosaccharide(COS) were estimated by titration of acid-base method as 90.9% and 90.1%,respectively.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.
