Abstract

The density functional theory (DFT) study of the Pb intercalation in the Montmorillonite was investigated. The influence of Al doping on the tetrahedral silicate layer and Mg doping on the octahedral layer of montmorillonite was analyzed. The change in geometric structure due to the Pb intercalation in the montmorillonite was observed. The results indicated that Pb is tend to be located on the ditrigonal surface of montmorillonite and it is near the area of doping atoms (Al. Mg). The intercalation of Pb creates the Pb-O bond formation.

Keywords: DFT, Pb, montmorillonite
