  • Analyze DSC data taken on 9/14/2012
  • Dilute 20 ppm SO4-2 stock solutions made on 9/19/2012 to be used for atomic absorption calibration
    • Dilute to 1ppm, 2ppm, 5ppm, 10ppm, 15ppm
  • Prepare a 500mL solution of 1.25g CuSO4 using HPLC grade H2O
  • Prepare more glutaraldehyde films
  • Prepare a thin PVOH film for use in FTIR
  • Run X-Ray diffraction of 2:1 NaMT:Fe2O4 clay dried on 9/19/2012\
  • Prepare glutaraldehyde fixant solution

Fixant Solution preparation

  1. Weigh out 200g Na2SO4 (actually measured out 200.1459g)
  2. Place in a 2000mL Erlenmyer flask
  3. Using a graduated cylinder, add 1000mL deionized H2O. Add a large magnetic stir bar to the flask
  4. Place Erlenmyer flask on a stir plate. Stir until all dissolves
  5. Add 20mL concentrated H2SO4
  • Note: H2SO4 is highly corrosive. Use extreme caution
    1. Gently mix solution and using a funnel pour the solution into four 250mL capped bottles
