122 citations



Journal ArticleDOI
TL;DR: In this paper, the position of the first charge transfer band is fixed for the metal ion in an oxygen coordination of VI, but varies in VIII coordination as a function of the host lattice.

Journal ArticleDOI
TL;DR: In this article, the crystal structure and atomic arrangement of uranyl acetate dihydrate, UO2(CH3COO)2·2H2O, have been determined by a single-crystal X-ray diffraction study.

Journal ArticleDOI
TL;DR: In this article, a general discussion of the Cs+ or Rb+-ion exchange behavior on zirconium phosphate at various degree of crystallinity is made, and it is concluded that the low, apparent selectivity of crystalline zircanium phosphate towards large monovalent ions is due to steric hindrance and therefore enlarged phases of this exchanger, such as Zr(HPO4)2.8H2O (10·4 A), are expected to have a high selectivity towards Cs+, or even larger cations.

Journal ArticleDOI
TL;DR: In this article, the rate of the forward reaction depends on the ratio of the total copper to free proton concentration in the aqueous phase and that of the reverse (stripping) reaction on the product of the copper concentration in organic phase and the free protons concentration in aqueouse phase.

Journal ArticleDOI
TL;DR: In this article, the half-lives of new nucleides have been determined: 75 Rb (21±3) sec, 76 Rb(36·8±1·5) sec and 116 Cs (3·6±0·2) sec.

Journal ArticleDOI
TL;DR: In this paper, the phases formed at elevated temperatures by α-zirconium phosphate (α-ZrP) and its partially exchanged sodium and potassium ion phases have been determined by a combination of thermal and X-ray methods.

Journal ArticleDOI
TL;DR: In this paper, three ion exchange processes are characterized by a sharp moving boundary between the reacted shell and the shrinking unreacted core within each ion-exchanger bead, which is controlled by the rate of diffusion of the ions penetrating the reacted layer.

Journal ArticleDOI
TL;DR: In this article, a method for calculating the overall stability constant, β 3(c ), of UO 2 (CO 3 ) 3 4− from the resultant distribution date is outlined.

Journal ArticleDOI
TL;DR: In this paper, complex solution chemistry associated with formation and growth of hydrous chromium(III) oxide particles of narrow size distribution was investigated, and the results indicate that two solute species are involved in solid formation, and that multi-component equilibria are established.

Journal ArticleDOI
TL;DR: In this article, the effect of the type of ligands on the energy levels and the bonding coefficients of the metal ions has been investigated and shown to be a function of the pyrrole/3 carbon positions.

Journal ArticleDOI

Journal ArticleDOI
TL;DR: The products of boiling hydrolysis of ferric chloride solutions have been compared with well-known iron oxide phases by the use of i.r.t. and Mossbauer spectroscopy, electron microscopy, and chemical reactivity.

Journal ArticleDOI
TL;DR: Tin(II) alkoxides (Sn(OR)2, R=CH3, C2H5 and C4H9) were synthesized and the molecular weight of the butoxy compound was determined in methylene chloride solution and indicates a dimeric substance as mentioned in this paper.

Journal ArticleDOI
TL;DR: The order of pH values at which different α-hydroxyoximes extract a given metal parallels the expected order of steric hindrance offered by the substituent alkyl groups to the formation of the metal complex.
