Book excerpt: Three precise calorimetric methods, viz., low-temperature adiabatic, high-temperatuare drop, and solution-reaction, have been used to determine as a function of temperature the key chemical thermodynamic properties of a pure sample of schoepite, UO2(OH)2 · H2O. The following results have been obtained at the standard reference temperature T = 298.15 K:standard molar enthalpy of formation [Delta]/sub f/H/sub m/°(T) = -1825.4 +- 2.1 kJ mol−1; molar heat capacity C/sub p, m/°(T) = 172.07 +- 0.34 JK−1; and the standard molar entropy S/sub m/°(T) = 188.54 +- 0.38 JK−1 mol−1. The molar enthalpy increments relative to 298.15 K and the molar heat capacity are given by the polynomials: {H{sub m}°(T) - H{sub m}°(298.15 K)}/(J mol−1) = -38209.0 + 84.2375 (T/K) + 0.1472958 (T/K)2 and C/sub p, m/°(T)/(JK−1 mol−1) = 84.238 + 0.294592 (T/K), where 298.15 K
Download or read book Chemical Thermodynamics of Uranium written by Ingmar Grenthe and published by Elsevier Science & Technology. This book was released on 1992 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive overview on the chemical thermodynamics of those elements that are of particular importance in the safety assessment of radioactive waste disposal systems. This is the first volume in a series of critical reviews to be published on this subject. The book provides an extensive compilation of chemical thermodynamic data for uranium. A description of procedures for activity corrections and uncertainty estimates is given. A critical discussion of data needed for nuclear waste management assessments, including areas where significant gaps of knowledge exist is presented. A detailed inventory of chemical thermodynamic data for inorganic compounds and complexes of uranium is listed. Data and their uncertainty limits are recommended for 74 aqueous complexes and 199 solid and 31 gaseous compounds containing uranium, and on 52 aqueous and 17 solid auxiliary species containing no uranium. The data are internally consistent and compatible with the CODATA Key Values. The book contains a detailed discussion of procedures used for activity factor corrections in aqueous solution, as well as including methods for making uncertainty estimates.

This book was released on 2003-11-04 with total page 976 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is part of the series on "Chemical Thermodynamics", published under the aegis of the OECD Nuclear Energy Agency, and updates and expands the thermodynamic data on inorganic compounds and complexes of uranium, neptunium, plutonium, americium and technetium contained in the previous volumes of the series. A review team, composed of seven internationally recognized experts, has critically reviewed during five years all the scientific literature containing chemical thermodynamic information for the above mentioned systems that has appeared since the publication of the earlier volumes. The results of this critical review carried out following the Guidelines of the OECD NEA Thermochemical Database Project have been documented in the present volume, which contains new tables of selected values for formation and reaction thermodynamical properties and an extensive bibliography.
