OBJECTIVES

  1. Prepare a PVOH film w/ a glutaldehyde deviation for film analysis
  2. Prepare clay samples w/ ratio and surfactant deviations for ion exchange experimentation
  3. 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
