To continue the porphyrin film salt tests | |||
==Description== | ==Description== | ||
# Remove the porphyrin film from the sodium sulfate solution. | |||
# Cut the film to the size of a cuvette | |||
# Measure the thickness of the film (2.6 mm) | |||
# Take a UV-Vis of the film. | |||
# Place the film into 2% wt H<sub>2</sub>SO<sub>4</sub> solution until it turns green | |||
# Remove the film from the acid solution and place it in the previously prepared aluminum sulfate solution. | |||

* 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 | |||
