Abstract
A simple, rapid and sensitive spectrophotometric method was developed for the determinationation of
trace amounts of iron (III) using 8-hydroxyquinoline as a chromogenic reagent. The proposed method
was based on the reaction of iron (III) with 8-hydroxyquinoline in chloroform solution to form a metaloxine complex having a maximum absorption at 359 nm. Beers law was obeyed in the range of 1 to 14
ug/ml Fe3+. The recovery was between 98.60 and 103.30% with a coefficient of variation of 1.209%. The
method was successfully applied to tap water samples and comparison with standard method showed
the new method to be accurate and precise as the more sophisticated AAS commonly used for Fe
determination.
