Abstract: This paper presents the study of synthesis of Polypyrrole nanocomposite from pyrrole monomer incorporating anhydrous Iron (III) Chloride as an oxidant using chemical oxidative polymerization method. The experiment was conducted over a period of 4 hours at a temperature of 50C with varied concentrations of FeCl3, oxidant to monomer ratio were ranging from 0.5 to 2.0. The reaction of polypyrrole with 1, 10-phenanthroline forms a complex, Spectrophotometer (EQ 820D) was used to investigate the maximum wavelength (?max) and to quantify the Ferrous Fe (II) ion content in polypyrrole solution using a colorimetric technique. Series of standard Fe solutions were formulated to establish the relationship between optical absorbance and Fe concentration. The presence of Fe(II) ions validated the process that led to the production of polypyrrole from its monomer. The current paper focuses on a simple and exact approach for estimating the Iron (II) content in polypyrrole.
