The Absorption Spectra of Complexes of Uranium (VI) with Some [beta]-Diketones

Description: Abstract: "The absorption spectra of the complexes of uranium (VI) with four [beta]-diketones were determined under various conditions of pH, concentration of uranium, and alcohol concentration. Under optimum conditions, the maximum molar absorptivity (31,200) is obtained using 2-furoyltri-fluoroacetone. This compares with about 4,000 and 19,000 for the thiocyanate and dibenzoylmethane complexes, respectively."

A Dithizone Method for the Determination of Lead in Monazite

Description: The following report discusses a method for determining lead in monazite to be used as a basis for geologic age measurements. In order to develop the method it was necessary to eliminate interferences due to the presence of phosphates of thorium and the rare-earth metals.

The Equation of Continuity in Geology With Applications to the Transport of Radioactive Gas

Description: From abstract: "The transport of matter by fluids percolating through a porous medium is described by setting up a mass conservation equation, analogous to that of hydrodynamics, for each of the substances in question... The results are applied to some selected data from the Texas Panhandle gas field."
