Objectives

  1. Continue testing the 30% Bentonite beads
  2. Test the 40% Bentonite beads

Procedure

  1. Testing the 30% Bentonite beads
    • The 30% Bentonite beads were tested using the same method as that from before.
  2. Testing the 40% Bentonite beads
    • The 40% Bentonite beads were tested using the same method as that from before.

Observations

  1. 30% Bentonite beads from solution:
    • Another 7 MG rinses were performed, bringing the total to 23 MG rinses.
  2. The 30% Bentonite beads are still absorbing all of the MG stock solution, further necessitating more MG rinses; however, we predict that only a few more rinses will be necessary before MG begins to elute from the beads.
  3. 40% Bentonite beads from solution:
    • 8 MG rinses were performed, further rinses will be necessary.
    • About 12 drops per minute
  4. The 40% Bentonite beads should take longer to elute MG from the column than the previous columns before it; therefore, we predict that many more MG rinses will be necessary.
