OBJECTIVES

Porphyrin Salt Selection and Preparations 2

SO₄^2- salts used:Fe₂SO₄, Al₃SO₄,FeSO₄,& Na₂SO₄

Preparing 10mM Stock Solutions For Each Salt :

1. Obtain four clean 100mL volumetric flasks with stoppers
2. Measure out calculated amounts of each salt to establish 10mM concentration
3. Add varied salt amounts to each volumetric flask (one salt per flask)
4. Fill each volumetric flask ½ full with HPLC grade H₂O
5. Swirl each flask thoroughly for ~ 5 minutes to begin the dissolving process
6. Finish adding HPLC grade H₂O to each volumetric flask to line

(Ensure that the volumetric calibration line is not surpassed or solution must be remade.)
