PVA-Clay Cation Exchange

  1. After centrifugation the clay was laid out on a watch glass and dried
  2. The dried clay was removed from glass and crushed using a mortar and pestle
  3. It was then transferred into a scintillation vial and massed 1.0484g of NaMT cation exchange powder
  4. The vial was placed into a oven in order to remove any excess hydrate
