Objectives

1. Finish running FTIR on remaining films.
2. Finish running UV-vis on porphyrin and sulfate salt solutions(must reprepare various concentrations)

FTIR

• The general protocol for FTIR was followed

Films ran FTIR on:

1. PVOH(22K) 1.0067g+1mL GA+1mL porphyrin crosslinked
2. PVOH(22K)+0.5mL GA+0.104g NaMT crosslinked spun 10 min CuSO4 prepared 10/17/2012
3. PVOH(22K)+0.5mLGA+0.99mL porphyrin(no color on film )crosslinked prepared 10/19/2012
4. PVOH(22K)+1mL GA+100%CEC crosslinked prepared 10/4/2012
5. PVOH(22K)+1mL GA+1mL porphyrin crosslinked prepared 10/24/2012
6. PVOH(22K)+0.5mL GA+1mL porphyrin crosslinked prepared 10/24/2012 #2
7. PVOH(22K)+0.5mLGA+1mL porphyrin prepared crosslinked 10/26/2012
8. PVOH(22K)+0.8wt% GA+100%CEC crosslinked spun 10 min CuSO4 prepared 10/26/2012
9. PVOH(22K)+0.8wt% GA+50% CEC crosslinked spun 10 min CuSO4 prepared 10/17/2012

UV-vis

• Prepared new porphyrin and sulfate salt solutions for UV-vis
• In all preparations HPLC grade H₂O was used
• 1.89μM porphyrine was added to 0.1mL, 0.2mL, 0.5mL or 1.0mL of salt
• 10mM Al₂(SO₄)₃, 10mM Fe₂(SO₄)₃, 10mM Na₂SO₄ and 10mM of FeSO₄ was for the solutions
• Four new solutions(using different amounts of the wanted salt) were prepared for each salt(either Al₂(SO₄)₃, Fe₂(SO₄)₃, Na₂SO₄, and FeSO₄) making a total of 16 new solutions prepared.
