Strontium adsorption was studied in an aluminum-pillared montmorillonite (PILC) carrying organic acid groups. The in situ dissociation of these groups increases the number of negative sites in the modified PILC, promoting thus the uptake of cations from an exchange solution. To investigate the role
Solid state magic angle spinning nuclear magnetic resonance (MAS NMR), together with microcalorimetry and XRD data, have been used to characterize a pillared interlayered clay (PILC) containing 1X3 Γ 10 Γ4 mol Keggin ionag PILC. The clay catalyst (Al 13 -PILC) was prepared by reacting a Texas Na-mon
