Spectrophotometric Determination of Zirconium and Hafnium with Uramildiacetic Acid
Sanjay Asthana | Swarn Lata Bansal
Abstract: The reactions of Zirconium (IV) and Hafnium (IV) with uramildiacetic acid (UDA) reagent have been studied spectrophotometrically and the stoichiometries of the ternary complexes have been determined. The method has been applied for direct determination of Hf (IV) and Zr (IV) with UDA in acidic medium. The absorption has been measured between 450 - 540 nm. Beer?s law is obeyed for Zr and Hf concentration of 0.1 - 5.0 ?g per ml. The molar absorbitivities of aqueous Zr and Hf complexes were 1.80 x 10 - 5 and 3.1 x 10 - 5molL - 1cm. This method is simple, fairly accurate, rapid and free from interference from most common metal ions. The accuracy and precision have exhibit to be adequate for zirconmatrices.
