Synthesis of Hydroxamic Derivatives of Carboxymethyl- and Carboxyethyldextran

摘要

Synthesis of polyligands and chemisorbents is of particular interest in the chemistry of modified natural polysaccharides. The cross-linked chitosan derivatives were proposed as complexing agents [1]. Derivatives of the starch dialdehyde dioximes and dihydrazones show high chelating ability in relation to a number of metals [2, 3].
