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

PXRD

  • Set up PXRD of PVA+Clay films at different concentrations.
    • Tray 1 -Clay powder-control
    • Tray 2 -8ppm by Madeleine
    • Tray 3 -2ppm by
    • Tray 4 -PVA film-control
    • Tray 5 -80ppm by Eleni
    • Tray 6 -200ppm by my group
      • Instrument Settings
        • 2o start angle
        • 40o stop angle
        • 1o/second scan speed (this seems too fast, will check on this)
        • 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)

Results

UV-Vis was performed on the solutions of MG started on September 12 and the results can be found in the graph and chart below.
