Completing Film Synthesis

Continued from Wednesday, 8/27/2014<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
    • 1.0039g PVA and 0.1128g sodium montmorillonite
  • Polymer Film
    • 1.0036g PVA

Malachite Green Stock Solutions

The groups made 0.2, 0.5, 1.1, 1.4, 1.7, 2.0, 8.0, 80.0, and 200.0 ppm malachite green solutions The ones assigned to us were 25 mL of 2.00 ppm and 1.7 ppm malachite green

  • 2.0ppm solution in 100 mL volumetric flask
    • (2.0ppm)(100mL)=(200.0ppm)*V
    • V=1mL of 200.0ppm solution in 99.0mL water
  • 1.7ppm in 25mL volumetric flask
    • (1.7ppm)(25mL)=(8.0ppm)*V
    • V=5.31mL of 8.0ppm solution in 19.69mL water

Take UV-vis measurements
