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."
