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.

PVOH(22K) + Furfural Film

• Please refer to Karlena Brown's entry for the protocol and observations.

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^-.
