Analytical Utility of the Unique Colour Reaction Between Uranyl Ions and Alizarin Fluorine Blue

The uranyl-alizarin fluorine blue chelate complex shows an absorption peak at 560 nm, 30 nm higher than that of any other single metal complex of the reagent. The complex shows, at pH 4.5, a conditional stability constant of 2.3 × 10 6 litres mole −1 and molar absorptivity of 4100 litres mole −1 cm...

Zusammenfassung:	The uranyl-alizarin fluorine blue chelate complex shows an absorption peak at 560 nm, 30 nm higher than that of any other single metal complex of the reagent. The complex shows, at pH 4.5, a conditional stability constant of 2.3 × 10 6 litres mole −1 and molar absorptivity of 4100 litres mole −1 cm −1 . Study of the feasibility of using this reaction for the photometric determination of Uo 2 +2 in both one and two liquid phase systems reveals serious interference from other metal ions.
