# | # Completing film synthesis | ||
## Warm 150mL of Sodium Sulfate Solution at 80C for 15 minutes | |||
## Place both films in Sodium Sulfate Solution at 80C for 1 hour with gentle stirring | |||
## Warm 150mL of 1% HCl at 80C for 15 minutes | |||
## Place both films in 1% HCl Solution at 80C for 30 minutes with gentle stirring | |||
## Place film in 150mL of Sodium Bicarbonate Solution for 15 minutes at room temperature with gentle stirring | |||
# Starting new film synthesis | |||
## Using [[User:Matt_Hartings/Notebook/AU_Biomaterials_Design_Lab/2014/08/27|Wednesday's Procedure]] to make new 10% clay-polyvinyl alcohol film | |||
### It was 10% by weight clay because we used 1.008g of PVA and 0.1103g of clay | |||
###The PVA without clay weighed 1.003g | |||
## We also made the following solutions | |||
### 25mL 0.20ppm Malachite Green | |||
### 25mL 0.50ppm Malachite Green | |||
### 25mL 1.1ppm Malachite Green | |||
### 25mL 1.4ppm Malachite Green | |||
### 25mL 1.7ppm Malachite Green | |||
### 50mL 2.0ppm Malachite Green | |||
### 50mL 8.0ppm Malachite Green | |||
### 50mL 80.0ppm Malachite Green | |||
### 50mL 200.0ppm Malachite Green | |||
## Take a UV-Visible spectrum of the 0.2ppm to 8ppm standards. | |||
## Make a standard curve to determine the molar absorptivity of Malachite Green | |||

*Complete film synthesis | |||
# 0.2M Sodium Sulfate Solution | |||
## I dissolved 22.034g of anhydrous Na<sub>2</sub>SO<sub>4</sub> in 1000mL of water | |||
## I added 100mL of concentrated H<sub>2</sub>SO<sub>4</sub> to this solution | |||
## This solution will be used to enable the reaction between polyvinyl alcohol and glutaraldehyde in order to cross link the polymer film | |||
# 1% wt. HCl Solution | |||
## I added 10mL of concentrated HCl to 985mL of water | |||
## This solution will be used to enable the reaction between polyvinyl alcohol and glutaraldehyde in order to cross link the polymer film | |||
# 0.2M Sodium Bicarbonate Solution | |||
## I dissolved 17.042g of NaHCO<sub>3</sub> in 1000mL of water | |||
## This solution will be used to neutralize the acid in your films | |||
