Fluorometric Determination of Uranium in Zirconium and Hafnium

Abstract

Wave length, 655 µ Slit width, 0.130 mm.Cell, 1-cm. Composition of final solution: Indicated volume of standard solution of KTcO< (0.207 mg. of Tc(VII)/ml.); 1.0 ml. of 10% v./v. thioglycolic acid solution of pH 8.0 ± 0.2; 1.0 ml. of 1M sodium acetate solution; and water, to make a total volume of 5.0 ml.

Fluorometric Analysis

“…Grigor'ev, Lukyanov, and Duderova (125) describe an electric furnace and a rapid method of preparing the fused beads. Particular techniques for separations from various sources occupy several papers, for example, from coal ashes, and rock samples (820), from zirconium and hafnium (387), from urine (3, 299, 407). Sagi and Rao (310) have devised a method for the determination of uranium wherein the uranium is reduced in a Jones reductor and titrated with ferric iron with rhodamine 6G as a fluorescent indicator.…”

Determination of V, Cr, Mn, Fe, Ni, Cu, Cd, Pb, and U in Zirconium Matrix by Inductively Coupled Plasma Mass Spectrometry Employing Microwave-Assisted Digestion and Matrix Separation by Synergistic Solvent Extraction

“…The determination of uranium in a zirconium matrix has been reported using time-resolved laser fluorescence spectrometry, fluorimetric, volumetric techniques, etc. (23,(49)(50)(51)(52)(53). Its determination in a zirconium matrix by ICP-MS has, however, not yet been reported until this date.…”
