Abstract

The color reaction of Fe(III) with Tiron (H2L) at different pH values was studied by spectrophotometry and conductometry. Fe(III) reacts with H2L to form 3 complexes: FeL+, FeL2-, and FeL33-, depending on the pH of the soln. The effective pH ranges over which the absorbances of the green, violet, and red colored complexes remain const. are 1.5-3.0, 5.8-6.8, and 8.7-11.5, resp. The max. absorption wavelength intervals are 660-680, 558-568, and 468-484 nm, resp. Beer's law was obeyed in the ranges 0-33, 0-7.25, and 0-8.9 ppm for the green, violet, and red complexes, resp. The molar absorptivities and stability consts. of the 3 complexes are given. [on SciFinder(R)]
