The utilization of intercalation process as suitable modelling method for the study of interaction metals-soils

Original language description

This contribution is focused on the intercalation of montmorillonites by hazardous metals Pb, Cd, Sn, Al. The intercalation of montmorillonites by Pb and Cd is type of simple cation exchange and the determined exchanged amounts of Pb2+, Cd2+ were in therange 0.8 - 1.2 mmol/g MMT, according to the type of montmorillonites. In the case of intercalation of montmorillonite by Sn and Al, the strong influence of pH (measured in range 0,8 -2,5 for Sn and 1,5 -4,1 for Al), due to formation various types of ionand complexes, was confirmed by the determined amounts of metal cations and interlayer cations for intercalation process. The factors (pH, concentration of Cl-, ion forms) were studied in this work too. The method ICP-OES and AAS were used for the determination of cations.
