I guess that was because you took the concentration of iron in spinach from the absorbance graph by extrapolating substantially. You did an absorbance graph for 0.194 1.113 whereas your absorbency for spinach is only 0.015. So there may be some potential for errors there. t.c Oct 14 '14 at 1754
This lab report is about the extraction of spinach and how the spinach contains different pigments that are seen in different colors. Also, each pigments have different solubilities, therefore, different eluents must be used while extracting the different pigments.

Extraction of ferredoxin from spinach leaves and its effect on Clostridium perfringens (anaerobe) growth A total of 19 trials were carried out to determine the suitable solvent for isolation of ferredoxin from spinach leaves. These were as follows iron content, using
Best way to prepare spinach for iron analysis Wash spinach, if bunsen burner and crucible are available, burn spinach and grind ashes but if not just cut and grind the spinach up as much as you possibly can; the finer the grind, the better the acid will access all of the iron to extract it (its job).
Spinach is a great source of Iron and copper. It is a healthy source of these minerals unless consumed in proper ammount. We analysed using colorimetric techniques the concentration of Iron and
The iron is in the form of iron powder, and can be extracted from a suspension of crushed cereal in water using a magnet. Lesson organisation This can be a class experiment or a demonstration as preferred.
