Original Abstract

Experimental results of sorption kinetics and equilibrium are compared with traditional Langmuir theory. Although, equilibrium data for sorption of metal ions on solid humic acids can be fitted relatively precisely by Langmuir isotherm, its utilization is connected with some inaccuracies, because it does not take into account the production of hydrogen ions during reactions of metal ions with acidic functional groups on the surface of humic particles. The new type of adsorption isotherm, respecting the nature of surface chemical interactions, was proposed for adsorption of metal ions on solid humic acids and proved experimentally.
