Kinetics of Sorption of Metal Ions on Lignitic Humic Acids

Original language description

Affinity of humic acids (HA) to heavy metals is well known. Many authors use copper as model metal for study of interaction with HA due to its high complexation ability and affinity to HA. My previous works showed that classical Langmuir isotherm, whichis frequently used for mathematical description of equilibrium sorption of metal ions on HA and determination of sorption capacity, 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. In view of the fact, that Langmuir isotherm is based on kinetics of sorption process, I develop new model for equilibrium sorption of metal ions on HA including splitting ofhydrogen ions in chemical sorption on acidic groups. The model was proved experimentally for sorption of cupric ions. This work deals with kinetics of sorption of cobalt and nickel ions on HA to prove above mentioned new model for metal
