Objective

To continue the porphyrin film salt tests

Description

1. Remove the porphyrin film from the sodium sulfate solution.
2. Cut the film to the size of a cuvette
3. Measure the thickness of the film (2.6 mm)
4. Take a UV-Vis of the film.
5. Place the film into 2% wt H₂SO₄ solution until it turns green
6. Remove the film from the acid solution and place it in the previously prepared aluminum sulfate solution.

Notes

• After sitting in the sodium sulfate the whole weekend, the porphyrin film had a light brown color.
• The porphyrin film was sort of falling apart, broke into 2 pieces one large and one small, we used the larger one
• High baseline occurs because the crosslinking makes the film not completely transparent
