Sorption of rubidium ions from aqueous solutions by activated carbons

Abstract

The adsorption of rubidium on different activated carbons has been studied as a function of
concentration of adsorbate, temperature and sorption time. The kinetic parameters of Rb+ sorption have
been determined. The sorption capacitances of investigated carbons with respect to rubidium ions have
been established. Various thermodynamics quantities namely H, S, G have been computed from
temperature dependences of rubidim adsorption on investigated carbons.
