30% clay beads prepared

Weighed columns

  • activated Carbon
  • 10%
  • 20%
  • 30%


  • Data for the columns prepared for MG adsorption next time. Columns were filled approximately halfway with beads.

  • 30% clay beads:

1.2505g PVA

1.25g PVA/7 * 3 = 0.0.5357g

0.5357g Bentonite * 97ml solution/3g bentonite = 17 mL bentonite solution

55mL solution - 10 mL bentonite solution - 15mL HCL: 23 mL H2O

  • Create a solution of with PVA, bentonite solution and water
  • Place this solution on a hot plate and heat/stir until everything has dissolved.
  • Add 5 mL of this solution to a 50 mL solution of ethyl acetate dropwise stirring at 380 rpm.
  • Add 0.5 mL of glutaraldehyde and stir at 400 rpm.
  • After 7 minutes, add 7 mL of sodium bicarbonate and stir for 30 seconds.
