OBJECTIVES
Porphyrin Salt Selection and PreparationsSO42- salts used:Fe2SO4, Al3SO4,FeSO4,& Na2SO4 Preparing 100mM Stock Solutions For Each Salt :
(Ensure that the volumetric calibration line is not surpassed or solution must be remade.) 100mM Salt Solution Calculations
MW Fe2SO4: 278.91 g/mol 100mM Fe2SO4 × (100mL H2O/1000mL H2O) × (278.91g Fe2SO4/1 mol Fe2SO4) = 2.7891g Fe2SO4
MW Al3SO4: 356.37 g/mol 100mM Al3SO4 × (100mL H2O/1000mL H2O) × (656.37g Al3SO4/1 mol Al3SO4) = 6.5637g Al3SO4
MW FeSO4: 278.01 g/mol 100mM FeSO4 × (50mL H2O/1000mL H2O) × (278.01g FeSO4/1 mol FeSO4) = 1.3901g FeSO4
MW Na2SO4: 142.04 g/mol 100mM Na2SO4 × (100mL H2O/1000mL H2O) × (142.04g Na2SO4/1 mol Na2SO4Na2SO4) = 1.4204g Na2SO4
UV-Vis Spectrum of Porphyrin with SaltsA specific porphyrin solution (944.5nM) was selected for exemplary UV - Vis analysis pertaining to each salt. Furthermore, 0.1mL each salt was combined with this particular porphyrin solution. Notes |
