STx-1 (Ca-rich Montmorillonite (white), Gonzales County, Texas,USA) |
| Preparation: |
converted to sodium montmorillonite by first dispersing the clay with 1 M NaCl, then siphoning the suspended <0.2 μm clay fraction by successively centrifuging and suspending the clay eight times in DI water. The suspension was flocculated with saturated NaCl, and excess solution removed via centrifugation. The clay suspension was then treated with a 1 M sodium acetate solution (pH 5) to remove residual carbonate minerals. The resulting Na-equilibrated montomorillonite was then centrifuged and equilibrated with the experimental background solution (10 mM NaCl), centrifuged again, dried at 70 °C overnight, and then gently powdered using mortar and pestle. |
