Spectrophotometric determination of iron with 1 10 phenanthroline

Two other reagents for the spectrophotometric determination of iron in highly alkaline media are 4,7dihydroxy-1,10-phenanthroline' and phenyl 2-pyridyl ketoxime3 for both the recommended reductant is sodium dithionite, a distinct disadvantage because of the tendency of dithionite solutions to form elemental sulphur.

Iron itself is not a huge absorber of light, but when it (in solution in the fe 2+ form) binds to 1,10 phenanthroline (c 12 h 8 n 2), it forms a highly stable red/orange-colored species by quantifying the color with spectrophotometry, we can deduce the concentration of iron in the solution and back-calculate the amount of iron in the original pill.
