Determination of uranium in the presence of iron and plutonium by Ti(III) reduction and biamperometric titration

A robust biamperometric titration methodology for the determination of uranium by Ti(III) reduction in the presence of plutonium

“…With the objective of eliminating the use of H 3 PO 4 in uranium determination, studies were undertaken to use a less complexing medium. These studies have resulted in the development of a simple, rapid and accurate method for uranium determination in H 2 SO 4 medium in the presence of plutonium and iron [4]. In this method, U(VI) is reduced to U(IV) in 0.5 M H 2 SO 4 + 0.5 M HNO 3 medium *Author for correspondence (E-mail: skaggr@barc.gov.in).…”

“…The excess Ti(III) is oxidized in the same medium by the controlled addition of 4 M HNO 3 . The rest of the procedure is the same as in the original method [4].…”

Electrochemistry of actinides on reduced graphene oxide: craving for the simultaneous voltammetric determination of uranium and plutonium in nuclear fuel

“…Redox titration methods, employing a visual indicator or electrometric end point detection, are widely used for the determination of uranium and plutonium independently in the uranium-plutonium mixed oxides. [11][12][13][14][15][16][17][18][19] The major issue in the quantitative redox titration of a mixed uranium-plutonium solution is the interfering redox reaction between U(IV) and Pu(IV) in acidic solutions. Following discussed redox titrimetric methodologies have been strategically developed to separately determine U and Pu avoiding their mutual interference.…”

Separation Behavior of U(VI) and Th(IV) on a Mixed Ion Exchange Column Using 2,6-Pyridine Dicarboxylic Acid as a Complexing Agent and Determination of Trace Level Thorium in Uranium Matrix Employing High Performance Ion Chromatography

“…Standard stock solution of uranium was prepared by dissolving nuclear grade U 3 O 8 and its concentration was determined by biamperometry method [35]. Standard stock solution of Th (97.8 mg ml…”
