Interfacial Tension Measurement on A1(NO₃)₃ - H₂O - HNO₃ - Dibutyl Cellosolve System (open access)

Interfacial Tension Measurement on A1(NO₃)₃ - H₂O - HNO₃ - Dibutyl Cellosolve System

This report discusses two methods used for experimental determination of the interfacial tension of an immisible aqueous-organic system where the density of the organic phase is less than that of the aqueous phase. The methods discussed are the falling drop method and the Donnan modification/rising drop method.

The Application of Tracer Techniques to the Determination of Uranium Extraction Coefficients (open access)

The Application of Tracer Techniques to the Determination of Uranium Extraction Coefficients

Abstract: This report deals with the development of a method using tracer technique for determining uranium extraction coefficients on solutions of low uranium concentration. It was found that extraction coefficients could be determined on systems containing as low as one part per million uranium using 1900 level uranium as the tracer. Results of several extraction series are presented in which aluminum nitrate is used as the salting agent and dibutyl carbitol the organic extractant.

General Report of Stable Isotope Separation (open access)

General Report of Stable Isotope Separation

Abstract: "The Calutron has been successfully employed to separate the stable isotopes of twenty-one elements. The standard Beta M-2 unit modified to handle charge materials of various temperature ranges has proven adequate for a majority of separations. The problem of K life has received considerable attention but is still to be solved. Other operational problems are similar in most respects to those of uranium. The E design has, of necessity, varied greatly from the "Beta Gloria" type. A desire to keep construction simple, yet adequate for efficient collection and readily adaptable for use with many elements, has dictated the trend in E design. Water cooling on the receiver pockets was necessary with many of the elements separated. The chemical purification of the separated samples, although following a general pattern, varies with the type of pockets used and the element collected."

Observed Differences in the Arc Spectra of U²³⁵ and U²³⁸ (open access)

Observed Differences in the Arc Spectra of U²³⁵ and U²³⁸

Abstract: "It has been found that the two principal uranium isotopes exhibit slightly different arc spectra. Certain U-235 lines have been found to be displaced from corresponding U-238 lines by about one reciprocal centimeter. The intensity ratio, IU235/IU238, has been shown to be a steadily increasing function of the U-235 concentration. These data indicate the possibility of developing a method for the determination of isotopic concentration by means of emission spectra."
