The selectivity of active carbons modified by fullerenes with respect to mixtures of metal cations in aqueous solutions

The separating ability of active carbons and active carbons modified with fullerenes with respect to mixtures of nonferrous metal cations was studied. The selectivity series for the extraction of cations from aqueous solutions was Ag⁺ > Cu²⁺ > Pb²⁺. The selectivity of adsorption by active carbon modified with fullerenes was higher than that characteristic of the initial adsorbent, especially for the extraction of silver ions from a mixture of silver and copper cations.
