Objectives

• Test Cu⁺² solutions with atomic absorption.
  • Generate a calibration curve from Cu⁺² standards.
• Crosslink films made on 2012/10/03.

PVOH Film Crosslinking

• The three films that were prepared on User:Melissa_Novy/Notebook/CHEM-581/2012/10/03 were crosslinked.
• Please refer to Moira Esson's entry for masses and volumes of crosslinking solutions used.
• Note that the two crosslinking solutions are 1% HCl in water and 0.2 M NaHCO₃.
  • There were no deviations from the standard crosslinking protocol.
  • About 0.5 g was cut from each film and then crosslinked. The rest of the film were saved for other analyses.

AAS Analysis

• The AA was found to be clogged with gold particles, so all measurements made on 2012/10/05 must be redone after the AA is properly cleaned.
