Objective

  1. To finish completing the film synthesis
  2. Start a new film synthesis
  3. Start and finish Malachite green stock

Description

  1. Completing film synthesis
    1. Warm 150mL of Sodium Sulfate Solution at 80C for 15 minutes
    2. Place both films in Sodium Sulfate Solution at 80C for 1 hour with gentle stirring
    3. Warm 150mL of 1% HCl at 80C for 15 minutes
    4. Place both films in 1% HCl Solution at 80C for 30 minutes with gentle stirring
    5. Place film in 150mL of Sodium Bicarbonate Solution for 15 minutes at room temperature with gentle stirring
  2. Starting new film synthesis
    1. Using Wednesday's Procedure to make new 10% clay-polyvinyl alcohol film
      1. It was 10% by weight clay because we used 1.008g of PVA and 0.1103g of clay
      2. The PVA without clay weighed 1.003g
    2. We also made the following solutions
      1. 25mL 0.20ppm Malachite Green
      2. 25mL 0.50ppm Malachite Green
      3. 25mL 1.1ppm Malachite Green
      4. 25mL 1.4ppm Malachite Green
      5. 25mL 1.7ppm Malachite Green
      6. 50mL 2.0ppm Malachite Green
      7. 50mL 8.0ppm Malachite Green
      8. 50mL 80.0ppm Malachite Green
      9. 50mL 200.0ppm Malachite Green
    3. Take a UV-Visible spectrum of the 0.2ppm to 8ppm standards.
    4. Make a standard curve to determine the molar absorptivity of Malachite Green
