Sorption when groundwater contaminating by heavy metals and radioactive elements. Zinc
The fourth issue of the series «Sorption processes at contamination of groundwater heavy me¬tals and radioactive elements» is devoted to the study of the adsorption / desorption behavior of zinc. The adsorption of heavy metal by soils has importance in determining of metal movement within the soil profile and their availability to the plant. Mechanisms of zinc retention and the effect of soil pH, macrocations, organic and inorganic ligands are of interest in this issue. Disposal of wastes such as municipal compost, waste incinerator slag and sewage sludge is a significant source of Zn applica-tion to land. One of the practical problems of this issue is to obtain information for the modeling
of zinc behavior in «water – rock» interaction and contamination of aquifer. It is then important to assess what specific factors are relevant in leaching behavior Zn. The review will be useful for pro-fessionals modelling processes of heavy metalscontamination in aquifer.
