Objective

To conduct clay-CuSO4 exchange, remake films with PDMS and glutaraldehyde, and prepare films containing clay (Na-MT and 100% CEC)

Description

Making films with PDMS and glutaraldehyde

Film 1

  1. 0.5 g of PVOH was dissolved in 5 mL of water and was placed on a hotplate
  2. 1 mL of glutaraldehyde was added to the solution under the hood.
  3. The mixture was allowed to stir for about 3 minutes.
  4. The film was poured into a dish and was left under the hood over the weekend


Film 2

  1. 0.4 g PVOH and 0.1262 g PDMS were dissolved in 5 mL of water on a hot plate.
  2. Once dissolved, 1 mL of glutaraldehyde was added to the PVOH/PDMS
  3. The mixture was allowed to stir without heat for 3 minutes
  4. The film was poured into a dish and was left under the hood over the weekend


Making clay films

Clay Film 1

  1. Weigh out 1 g PVOH (1.068 g actual) and .1 g Na-MT (0.1069 actual)
  2. Dissolve in 6 mL of water in a small beaker with a small stir bar
  3. Place on heated hotplate until it has become a homogenized mixture
  4. Add 1 mL of glutaraldehyde and stir for 3 minutes.
  5. Pour into a small plastic dish and leave under the hood to dry over the weekend

Clay Film 2

  1. Weigh out 1 g PVOH and .1 g 100% CEC surfactant clay
  2. Dissolve in 6 mL of water in a small beaker with a small stir bar
  3. Place on heated hotplate until it has become a homogenized mixture
  4. Add 1 mL of glutaraldehyde and stir for 3 minutes.
  5. Pour into a small plastic dish and leave under the hood to dry over the weekend


Clay-Copper Sulfate Exchange

  1. Three samples, each with 0.1 g of clay was measured out for the Na-MT, 100% CEC, 50% CEC, and Na-MT coated iron oxide
  2. Each sample was placed in 10 mL of copper sulfate solution that was previously prepared.
  3. The samples were stirred in the copper sulfate for either 1, 5, or 10 minutes.
  4. The samples were then filtered. Both the filtrate and the filter paper were saved.


Data

No data was collected today.

Notes

  • The filtrates collected will be used to prepare solutions for atomic absorption analysis.
