Abstract

The dissociation constants for pyridoxine hydrochloride have been determined both potentiometrically and spectrophotometrically at an ionic strength of 0·50M-KCl and at 30°. The interaction of the uranyl ion with pyridoxine had been studied spectrophotometrically in the pH range 1–12, at an ionic strength of 0·50M-KCl, and at 30°. It is shown that three mononuclear complexes are formed in the pH range 1–7·5, the pK values for the three stepwise instability constants being 11·49, 8·48, and 3·76. Data in the pH range 7·5–12 could not be interpreted adequately.
