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).
