OBJECTIVES

  • Make porphyrin solution with varied SO42- salts to uncover UV-Vis limit of detection (LOD)
  • Take UV-Vis of porphyrin solution with diluted varied SO42- salts

UV-Vis Limit of Detection For Salts

To find the limit of detection for the 10mM salts(Fe2(SO4)3, Al3(SO4)3, FeSO4, & Na2SO4) originally prepared 10/26/12, UV-Vis was run for each salt at various volumes added to a prepared porphyrin solution. A total of 16 solutions were prepared.

Solution of 1.89 μM porphyrin 

  (94.45 μM)(V1)=(1.89 μM)(10mL)
   V1 = 0.2mL of 94.45 μM porphyrin
