Objective

  • Make 50% beads
  • Continue collecting MG adsorbance data

Description

  • 50% clay beads:

1.25g PVA

1.25g PVA = 1.25 g clay

1.25g Bentonite * 97ml solution/3g bentonite = 40 mL bentonite solution

55mL solution - 40 mL bentonite solution - 15mL HCL: 0 mL H2O

  • Create a solution of PVA and bentonite solution.
  • Place this solution on a hot plate and heat/stir until everything has dissolved.
  • Add 5 mL of this solution to a 30 mL solution of ethyl acetate dropwise stirring at 380 rpm.
  • Add 0.5 mL of glutaraldehyde and stir at 400 rpm for 3 minutes.
  • After 7 minutes, add 7 mL of sodium bicarbonate and stir for 30 seconds.


Notes

For activated carbon, switched to water to rinse after 35mL. Activated Carbon first turned blue after 15mL.

For the 10% clay, blue only started to show after 135 mL.

Started using new cuvettes because we ran out of the first kind after 85mL (after 10 rinses) of the activated Carbon and 130mL (26 measures of MG) for the 10% carbon. New calibration curves were taken and final data has been adapted.
