摘要

Using the method of IR spectroscopy it was ascertained that in pectinates and alginates of polyvalent metals the coordination bonds between cations Pb2+, Cu2+, Zn2+, Cr3+, Mn2+, Fe2+, Co2+, Ni2+ and the oxygen atoms of carboxyl and hydroxyl groups, pyranose cycle and glycosidic linkage of polyuronides, the water molecules are formed. It was also ascertained that Cu2+ cations form asymmetrical structures with carboxyl groups of polyuronides (monodentate ligands) and cations of other metals—symmetrical structures with carboxyl groups of polyuronides (bidentate ligands).
