The behavior of Pa (IV) during extraction with TTA was investigated in perchlorate, chloride, and sulfate solutions (pH 0.4–1.1). In perchlorate and chloride solutions, the extraction equilibrium may be written as:Pa(OH)_2^2++4HTightleftharpoonsPaT_4+2H_2O+2H^+On the other hand, the extraction by TTA from the sulfate solution may be described as:Pa(SO_4)(OH)^++4HTightleftharpoonsPaT_4+HSO_4^-+H_2O+2H^+Therefore, the formation of the sulfato-complex of Pa(IV) is considered to occur as follows:Pa(OH)_2^2++HSO_4^-ightleftharpoonsPa(SO_4)(OH)^++H_2OThe equilibrium constant for the above reaction has been determined to be 320 at the ionic strength of 0.50 (temperature: 10±0.5°C).

The absorption spectra of trivalent uranium in hydrochloric, sulfuric and perchloric acid solutions were investigated. It was found that there is a possibility of the formation of a chloro-complex from the fact that a large change in absorption spectra was observed at high concentrations of chloride ion. On the basis of the above facts, the behavior of trivalent uranium in those media toward ion exchange resin was studied. It was considered that an anionic complex of trivalent uranium begins to form at concentrations of hydrochloric acid above 7 N, which shows good agreement with results obtained on trivalent ions of plutonium, americium and curium, which are similar actinide elements. However, it was not possible to confirm the existence of a soluble carbonate complex of trivalent uranium, as in the case of trivalent plutonium or americium.

The infrared spectra of thin urea and thiourea films, several hundred Angstroms thick, on a steel plate were obtained using an optical system in which the beam polarized parallel to the plane of incidence was incident at 70° upon a steel plate covered with film. The spectra obtained showed that the c-axis of the urea crystal was parallel to the metal surface. However, the abnormal behavior of the NH2 bending and the NH2 twisting bands suggests that the urea molecule in the film was deformed from the planar structure. The intensities of the infrared bands of thiourea belonging to the B1 species decreased in the film, and it may be concluded that the c-axis of the crystal is nearly parallel to the metal surface. The considerable rise in frequency of the NH2 wagging band observed in the thin thiourea film may arise from the deformation of the crystal. As for the thioureacollodion film, thiourea A1 bands appeared to be very weak, corresponding to the C=S bond orientation parallel to the metal surface. The dic...

The variation with temperature of paramagnetic susceptibilities of several alloys of In-Mn, Sn-Mn, Sb-Mn and Bi-Mn systems in their liquid states has been investigated. It obeys a Curie law in the range of temperature up to 1000°C for compositions less than about 15 atomic percent manganese. The Bohr magneton numbers derived from the experiment lie between 4.5 and 5.2, and their dependence on manganese concentration is discussed.

The behavior of pentavalent protactinium in sulfuric acid solutions was investigated by paper electrophoresis and by the TTA-benzene extraction method. From the results of this investigation, it is recognized that the Pa(OH)2(SO4)+ ion exists predominantly in dilute sulfuric acid solutions (pH 0.4–2.2), and that the complexing reaction of pentavalent protactinium by the sulfate ion may proceed as;Pa(OH)4++2H++SO42−ightleftarrowsPa(OH)2(SO4)++2H2O.The stability constant of Pa(OH)2(SO4)+ was also determined by the solvent extraction method to be 6.4 at an ionic strength of 1.38.

The experimental study of residual resistivity and magnetic susceptibility of dilute alloys of nickel in liquid bismuth is presented. The increase in resistivity by the addition of one atomic percent nickel amounts to 0.45 µΩ cm. The localized electrons of nickel are non-magnetic in liquid bismuth and the increase in the susceptibility by d -state of additional one percent nickel is 0.2×10 -6 C. G. S. e. m. u . It is concluded that the density of the virtual bound state of nickel in liquid bismuth is not so large compared with that of the conduction electron.
