  • Polymer-10% Clay Film
    • g PVA and g sodium montmorillonite (~1g PVA and ~.1g NaM)
  • Polymer Film
    • g PVA (~1g)

Exchanging Sodium in NaMT for Organic Cation

Procedure detailed by Dr Hartings.<br.> Assuming 92 miliequivalents (meq) of Na+ per 100g of montmorillonite.<br.>

  1. Add 1.12g of Sodium Montmorillonite (NaMT) to a scintillation vial containing 20mL of 50:50 HPLC grade water:ethanol.
  2. Add 0.523g of tributylhexadecylphosphonium bromide to exchange 100% of the Na from the clay
  3. Cap the vial
  4. Stir for 1 week
  5. Vacuum filter using 0.2uM nylon filter paper
  6. Dry in oven at 90C overnight
  7. Grind with a mortar and pestle
  8. Store in a dessicator
