Description

  • Measure MG new data through UV-Vis
  • Film Processing
  • Filter stirring clay in centriuge
    • 4000rpm for 30 minutes at 4C for original separation
    • with water then ethanol for 10 minutes
    • repeat for another cycle and dried done by Dr. Hartings
  • Set up PXRD of PVA+Clay films at different concentrations
  1. 1-Clay powder-control
  2. 2-8ppm by Madeleleine
  3. 3-2ppm by
  4. 4-PVA film-control
  5. 5-80ppm by Eleni
  6. 6-200ppm by my group
    1. Instrument Settings
      1. 2o start angle
      2. 40o stop angle
      3. 1o/second scan speed (this seems too fast, will check on this)
      4. 0.5o sampling width

Calculations

  • Dilutions of MG solutions
    • 200ppm*0.2mL=8ppm*5mL(vial with PVA film)
    • 80ppm*0.5mL=8ppm*5mL(vial with no film)
    • 80ppm*0.2mL=8ppm*2mL(vial with PVA film)
