Abstract

A comparative study of the determination of iron in iron tablets was carried out using colorimetric and titrimetric methods of
analysis. The work presented here reports on optimization of phenanthroline method. The maximum absorbance was found to be at
520nm wavelength. A calibration curve was found to be linear up to the concentration range of 0.8 μg/ ml to 3.60 μg/ ml and 10
μg/ ml. total three pharmaceutical samples from different pharmaceutical companies were analyzed and results were compared
with the results obtained by standards. The study showed that the total iron concentration in pharmaceutical samples. These values
are in good agreement with pharmacopeia range.
