Determination of plutonium by sodium bismuthate oxidation

Determination of plutonium by sodium bismuthate oxidation. Rao, V. K.; Charyulu, M. M. (Radiochem. Div., Bhabha At. Res. Cent., Bombay 400085, India). Proc. Nucl. Chem. Radiochem. Symp., Meeting Date 1981, 269-71. Dep. At. Energy (India): Bombay, India. (English) 1983. CODEN: 52ICAN. DOCUMENT TYPE: Conference CA Section: 71 (Nuclear Technology) Section cross-reference(s): 79 Accurate detn. of Pu is essential for chem. quality control of nuclear fuels, material inventory, etc. A method is described for accurate detn. of Pu based on the Pu(IV)/Pu(VI) couple. Na bismuthate [12232-99-4] was used, as it is a powerful oxidant (E0 = ~1.6 V), to oxidize Pu to the hexavalent state. Fe(II) was used for the redn. of Pu(VI) since it restricts the interference of U(VI).

Express analysis of rocks for manganese under field conditions

Express analysis of rocks for manganese under field conditions. Rogov, V. S.; Galitskaya, E. I. (VSEGEI, Leningrad, USSR). Razved. Okhr. Nedr, (2), 58-9 (Russian) 1984.Several reagents with their cas registry numbers 12232-99-4 and 7439-96-5 are used here. CODEN: RZONAV. ISSN: 0034-026X. DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Mn(II) present in rocks as carbonate and sulfide is detd. colorimetrically by oxidn. of Mn2+ to MnO4- with NaBiO3 after sample dissoln. with HNO3 and comparison of the color formed with std. solns. when HCl dissoln. is necessary, the interference of Cl- is eliminated by using a large excess of NaBiO3. This semiquant. method is advantageous for field use because the reaction proceeds without heating and the color intensity does not change over a long period of time. .
