Determination of ferrous ion in pharmaceutical preparations through planar chromatography and spectrophotometry

Abstract

The authors have studied the chromatographic behavior of pharmaceutical preparations obtained from commercial sources containing the ferrous ion. Using microcrystalline cellulose , propanol: 4 N, H Cl, acetic acid, nitric acid, chloroform mixture (40: 5: 5: 10: 10) as chromatographic system and and Alyzarin as the detection reagent Fe (II), Mn (II), Mg(II), Zn (II) and Ca (II) were separated and identificated by Planar Chromatography. Fe (II) cation was determined by reaction with 1, 10-Phenanthroline, resulting in an appropriate solution for colorimetric quantitation.
