Objectives

• Prepare crosslinked and uncrosslinked film samples for DSC.
• Exchange (2:1) Na-MT:Fe₃O₄ with CuSO₄ solution for 1, 5, and 10 min.
  • Dilute the filtrate to 7.4 ppm and 10 ppm for analysis with AA.
• Redo AA analysis on all Na-MT/CuSO₄ filtrate solutions.

DSC on PVOH Films

Cu⁺² Exchange with CuSO₄ and (2:1) NaMT-Fe₃O₄

• Three 0.1 g samples of (2:1) NaMT-Fe₃O₄ were weighed out.
• There were no changes to the Cu⁺² exchange protocol.
• The filtrate from each sample was diluted into 12 mL solutions of 7.4 and 10 ppm Cu⁺² with pure H₂O.
