Synthesis and characterisation of dioctahedral smectites.

, 2004
The synthetic clays are used in a lot of studies to analyse clay properties. They permit to have samples without impurities and with a specific chemical composition. In synthetic smectite group, trioctahedral smectites as saponite were generally studied.

Selectivity of Na-Montmorillonite versus Concentration of Two Competitive Bivalent Cations (Cu2+, Pb2+): Quantitative XRD Investigation

Advances in Materials Science and Engineering, 2009
The goal of this paper is to examine, by quantitative XRD analysis, the effect of heavy metal cation concentrations (Pb2+, Cu2+) on the selectivity phenomenon in the case of dioctahedral smectite (i.e., Na-montmorillonite).
