*Prepared new porphyrin and sulfate salt solutions for UV-vis | |||
*In all preparations HPLC grade H<sub>2</sub>O was used | |||
*1.89μM porphyrine was added to 0.1mL, 0.2mL, 0.5mL or 1.0mL of salt | |||
*10mM Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>, 10mM Fe<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>, 10mM Na<sub>2</sub>SO<sub>4</sub> and 10mM of FeSO<sub>4</sub> was for the solutions | |||
* Four new solutions(using different amounts of the wanted salt) were prepared for each salt(either Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>, Fe<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>, Na<sub>2</sub>SO<sub>4</sub>, and FeSO<sub>4</sub>) making a total of 16 new solutions prepared. | |||
