Abstract

Thiopicolinamide and pyridine-2, 6-dithioamide were investigated as spectrophotometric reagents for iron. Both reagents form soluble blue colored species with iron (II) ion in basic solutions. The tris-thiopicolfuarnide-iron (II) complex exhibits a wavelength of maximum absorption at 615 mμ with a molar absorptivity of 13,600. The bispyridine-2, 6-dithioarnide-iron (II) complex exhibits a wavelength of maximum absorption at 600 mμ with a molar absorptivity of 21,000. A sensitive method for the determination of iron based upon the latter complex is proposed.
