Ferrous and Ferric Complexes with Pyridine 2-Aldoxime

Abstract

PYRIDINE 2-ALDOXIME forms well-defined coloured complexes with ferrous and with ferric ions in aqueous solution. The ferrous complex is violet-red in alkaline solution (with an absorption maximum at 530 mμ), reddish-orange in slightly acidic solution (with a maximum at 515 mμ), and golden-yellow below pH. 3 (with a maximum at 475 mμ). The ferric complex is… (More)
