Objective
- Make 1:1 ratio of sulfate ions solution ( H2SO4, Fe2(SO4)3, FeSO4, Na2SO4, Al2(SO4)3).
- Adsorption through films similar to clay films instead of clay :
- 1.04 g Fe(II) Cl, 0.5 g Iron Sulfate, 1 film, and 40 ml H2O.
- To precipitate iron oxide out of the solution NaOH ( 2.67 g in 10 ml H2O) was added drop wise with stirring.
- The solution was then filtered using vacuum filtration and left to dry.
- Add film with Porphyrin and glutaraldehyde to 1% solution of HCl and leave out until the next working day.
Description
Sulfate (SO4 2-) as generated by the following solutions along with the porphyrin solution were prepared. The absorbance was measured for each one between by using the UV-Vis instrument by Shimadzu and the selected wavelength range in nm was [200 nm- 800 nm]:
- 1mL of 50μM Na2SO4 was dissolved in a 1mL of 5μM porphyrin solution and 2 mL HPLC graded water was used
- 1mL of 50μM Fe2(SO4)3 was dissolved in a 1mL, 5μM porphyrin solution and 2 mL HPLC graded water was used
- 1mL of 50μM FeSO4 was dissolved in a 1mL, 5μM porphyrin solution and 2 mL HPLC graded water was used
- 1mL 50μM H2SO4 was dissolved in a 1mL, 5μM porphyrin solution and 2 mL HPLC graded water was used
- 1mL 50μM Al2(SO4)3 was also dissolved in a 1mL of a porphyrin solution and 2 mL HPLC graded water was used.
