Objective

Take UV-Vis Measurements of Sulfate/Porphyrin solutions

Description

The following sulfate/porphyrin solutions were prepared and the absorbance was measured for each one between 200 and 800 nm:

1) 1mL 50μM Na2SO4, 1mL 5μM porphyrin, 2 mL HPLC H2O

2) 1mL 50μM Fe2(SO4)3, 1mL 5μM porphyrin, 2 mL HPLC H2O

3) 1mL 50μM FeSO4, 1mL 5μM porphyrin, 2 mL HPLC H2O

4) 1mL 50μM H2SO4, 1mL 5μM porphyrin, 2 mL HPLC H2O

5) 1mL 50μM Al2(SO4)3
