Data on the sorbability of ions of heavy metals (lead, cobalt, cadmium, zinc, copper, nickel) from Ringer’s solution with complex composition by untreated SKS synthetic carbons and those modified with nitrogen and sulfur were obtained. Exploratory studies of the sorption of complex anions of copper and iron with complexing ligands (Cl and CN) were performed. Selectivity series of toxic metals were determined on the basis of their calculated distribution coefficients. It was shown that the best sorption effect is due to the presence of nitrogen atoms and strongly acidic SO3H groups in the carbon structure.
