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.

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.
