Objectives

  • Analyze all films made since 2012/08/31 with FTIR.
  • Make a film of PVOH (MW 22000) and 5-hydroxymethyl(furfural) with HCl.
  • Make more concentrated porphine solutions with Al+3, Fe+3, or Na+2 salts for UV-vis analysis.
  • Conduct ion diffusion analysis on PVOH(22K) + 1 mL GA films exchanged for 10 min with CuSO4.

Ion Diffusion Analysis

  • Please refer to Karlena Brown's entry for the ISE conductivity protocol and observations.
    • Note that the varied ion solution contained 1000 ppm each of Cl-, Br-, and I-.
