<u>Making films with PDMS and glutaraldehyde</u> | |||
Film 1 | |||
# 0.5 g of PVOH was dissolved in 5 mL of water and was placed on a hotplate | |||
# 1 mL of glutaraldehyde was added to the solution under the hood. | |||
# The mixture was allowed to stir for about 3 minutes. | |||
# The film was poured into a dish and was left under the hood over the weekend | |||
Film 2 | |||
# 0.4 g PVOH and 0.1262 g PDMS were dissolved in 5 mL of water on a hot plate. | |||
# Once dissolved, 1 mL of glutaraldehyde was added to the PVOH/PDMS | |||
# The mixture was allowed to stir without heat for 3 minutes | |||
# The film was poured into a dish and was left under the hood over the weekend | |||
<u>Making clay films</u> | |||
Clay Film 1 | |||
# Weigh out 1 g PVOH (1.068 g actual) and .1 g Na-MT (0.1069 actual) | |||
# Dissolve in 6 mL of water in a small beaker with a small stir bar | |||
# Place on heated hotplate until it has become a homogenized mixture | |||
# Add 1 mL of glutaraldehyde and stir for 3 minutes. | |||
# Pour into a small plastic dish and leave under the hood to dry over the weekend | |||
Clay Film 2 | |||
# Weigh out 1 g PVOH and .1 g 100% CEC surfactant clay | |||
# Dissolve in 6 mL of water in a small beaker with a small stir bar | |||
# Place on heated hotplate until it has become a homogenized mixture | |||
# Add 1 mL of glutaraldehyde and stir for 3 minutes. | |||
# Pour into a small plastic dish and leave under the hood to dry over the weekend | |||
<u>Clay-Copper Sulfate Exchange</u> | |||
# 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 | |||
# Each sample was placed in 10 mL of copper sulfate solution that was previously prepared. | |||
# The samples were stirred in the copper sulfate for either 1, 5, or 10 minutes. | |||
# The samples were then filtered. Both the filtrate and the filter paper were saved. | |||
