OBJECTIVES
- Prepare a PVOH film w/ a glutaldehyde deviation for film analysis
- Prepare clay samples w/ ratio and surfactant deviations for ion exchange experimentation
- Learn process of extracting and filtering out given magnetite (α – Fe3O4) sample in clay using vacuum filtration
Glutaldehyde Film Safety
Preparing Glutaldehyde Film
- In 10mL beaker, weigh out ~ 0.5 grams PVOH (MW 22K)
(Actual Mass = 0.5141g)
- Then, using a graduated cylinder add ~ 5 mL H2O to the beaker
- After adding and combining PVOH (MW 22K) in a small beaker with H2O, add a stir bar and prepare to stir solution
- On hot plate, stir and heat beaker solutions at 70-80°C for ~ 12 min or until PVOH dissolves
- Once PVOH solids thoroughly dissolve in solution, take the solution and place it in the fume hood
- Allow the solution to cool to 40-50°C in the fume hood, and then add 0.5 mL 8% glutaraldehyde to the solution
- Then pour the solution into a Teflon dish to sit, cool, and dry in the fume hood for ~ 2 days
