Abstract

A Novel, rapid, sensitive and selective spectrophotometric method, using 4-aminoantipyrine (AAP) as an electrophilic coupling reagent and iminodibenzyl (IDB) as a chromogen, is proposed for the determination of trace amounts of iron(III) in water, industrial effluent and soil samples. The method is based on the reduction of iron(III) by AAP, which subsequently couples with IDB in a mild hydrochloric acid medium to form a blue coloured product having λmax at 620 nm. The colour is stable up to 24 h and obeys Beer’s law in the concentration range of 0.2 - 4.8 µg ml-1. The optimum reaction conditions and other important analytical parameters were established to enhance the sensitivity of the proposed method. The interference due to various non- target ions was also investigated. The proposed method was applied to the analysis of iron(III) in water, industrial effluent and soil samples. The performance of the proposed method was evaluated in terms of student’s t-test and variance ratio F-test that indicated the significance of the proposed method over reference spectrophotometric method.
