Selectivity of Na-Montmorillonite versus Concentration of Two Competitive Bivalent Cations (, ): Quantitative XRD Investigation
Figure 1
Best agreement between experimental (—) and theoretical (***) XRD patterns obtained for decreasing normality (i.e., 10-2 N(c), 10-3 N(b) and 10-4 N(a)) in the case of (0.5 Cu2+ and 0.5 Pb2+) solutions. d001 are given in(Å). Rp: goodness of fit parameter. The gray bar (Int X15) indicates a modified scale factor for the high-angle region. (*): Laurionite (PbOHCl) pat ref 74-2022(c).
