Procedures

Completing Film Synthesis

Continued from Friday, 8/29/2014<br.> Procedure detailed by Dr Hartings

  • Stir in Sodium Sulfate, 1% HCl, and Sodium Bicarbonate solutions

Beginning New Film Synthesis

Procedure detailed by Dr Hartings

  • Polymer-10% Clay Film
    • 1.0004 g PVA and 0/1077 g sodium montmorillonite (~1g PVA and ~.1g NaM)
  • Polymer Film
    • 1.0050 g PVA (~1g)

UV-vis Measurements

  • Take UV Vis spectra for Malachite green at the following concentrations: 0ppm, 0.20ppm, 0.50ppm, 1.1ppm, 1.4ppm, 1.7ppm, and 2.0ppm
  • Construct calibration curve for each of the two absorbance maximums

<br.>

Equilibrium Measurements

  • Dilute 200 ppm solutions 100x and 80 ppm solutions 50x to 10 mL & transfer to glass test tube (3 mL needed for absorbance measurements)

  • Determine the amount of Malachite green absorbed into a film
  • Determine the equilibrium of free Malachite green vs bound malachite green with I.C.E. table
  • Determine the mass of malachite green absorbed per mass of film
