Metal-binding ability of sodium alginate relative to Fe³⁺ and Cu²⁺ ions

Abstract

The article substantiates and experimentally confirms the possibility of a non-starch polysaccharide – sodium alginate to form complex compounds with iron (III) and copper (II) ions. Alginates are used in medical practice as an enterosorbent for severe poisoning with metal ions due to their ability to form complexes with heavy metals, insoluble in water.
