Objective

  1. Finish compiling data from the DSC
  2. UV-Vis of the MG PVA films
  3. Worked on ionic liquid exchange
  4. Started XRD of the MG PVA-Clay Films
  5. finished exfoliated clay film

Description

  1. Data collection from the DSC was completed
    1. a table of values and graphs of the temperature vs. heat flow can be seen below
  2. UV-Vis of the MG PVA films
    1. the data previously collected from the absorption of the PVA only films seemed off when compared to values with the class.
    2. New films were produced, allowed to absorb concentrations of Malachite Green, and UV-Vis was run on the different concentrations.
    3. Information on the new experiment can be viewed here.
  3. Ionic Liquid Exchange
  4. Started the XRD of the MG PVA-Clay Films
    1. Dr. Hartings produced the clay control in slot 1
      1. Madeleine's group produced the 8ppm sample in slot 2
      2. My group produced the 2ppm sample in slot 3
      3. My group produced the PVA film control in slot 4
      4. Eleni's group produced the 80ppm sample in slot 5
      5. Tami's group produced the 200ppm sample in slot 6
  5. Finished exfoliated clay film
    1. The procedure followed the standard film synthesis. This may be viewed here.

Notes

Exfoliated Clay Film A beaker of heating Sodium Sulfate was spilled in the hood and shorted the electricity.

  • The sodium sulfate solution was kept at room temperature with no stirring
  • When transferred to HCl solution, the temperature fluctuated between 75°C and 90°C with stirring
  • Sodium bicarbonate solution was not stirred
