The Separation and Fluorescent X-Ray Spectrometric Determination of Zirconium, Molybdenum, Ruthenium, Rhodium, and Palladium in Solution in Uranium-Base Fissium Alloys.

Abstract

metric 1 to 1 chelate. Binding of the second metal ion produces the symmetrical fluorescent structure, which is analogous to H3A-3 in configuration. The strong hypsochromic shifts which accompany the fluorescent changes indicate that the M-0 bonds of these metals are primarily ionic (15).

Determination of nonionic surfactants by atomic absorption spectrophotometry

“…These results show that the concentration of nonionic surfactant in solution can be measured by determining the molybdenum concentration in the residual reaction mixture by atomic absorption spectrophotometry. However, as in the classical method of measurement (7,2), the nonstoichiometric nature of the reaction between the surfactant, barium chloride, and phosphomolybdic acid means that the empirical relationship between the amount of phosphomolybdic acid reacted and the amount of surfactant present can only be determined when the type of surfactant and the composition of the solution containing it is known or a placebo is available. Table III gives some indication of variation in empirical factor to be expected between batches of the same surfactant, Table V the variation between types of surfactants, and Table I the variation due to changes in the inorganic composition of a multicomponent solution which contains the surfactant.…”
