The main objective of this study is to determine the structural characteristics of synthetic Na-Hectorite (H-Na) exchanged with heavy metals: Ni 2+ , Pb 2+ , Zn 2+ , Cd 2+ , Co 2+ and Mg 2+ using quantitative analysis based on the comparison between the theoretical and experimental XRD patterns. The different complexes are not homogenous. The hectorite saturated by the lead and cadmium present a segregation distribution of the layers, where as the others complexes present a random distribution.
