STUDY OF CHEMISTRY OF SORPTION OF IRON (III) CATIONS BY CARBON-CONTAINING COMPOUNDS
A thermally modified sorbent based on shungite of the Zazhoginskoje deposit (Karelia) was obtained. A comparative study of iron (III) sorption on the sorbents obtained was carried out, dependences of specific sorption of iron (III) on the equilibrium concentration were plotted. The degree of extraction of the metal cation from the model solution by using the original and modified natural sorbents was determined.
