Available in PDF, EPUB and Kindle. Book excerpt: A study has been made of the elution behavior of curium(III), americium(III), plutonium(III), actinium(III), plutonium(IV), neptunium(IV), uraniuM(IV), thorium(IV), neptunium(V), plutonium (VI), uranium (VI), lanthanum(III), cerium(III), europium(III), ytterbium(III), ytterium(III), strontium(II), barium(II), radium(II), cesium(I) with 3.2 M, 6.2 M, 9.3 M, and 12.2 M HCl solutions from Dowex-50 cation exchange resin columns. These elutions show that in high concentrations of hydrochloric acid the actinides form complex ions with chloride ion to a much greater extent than the lanthanides. The strengths of the tripositive actinide complex ions apparently go in the order plutonium > americium> curium, although their ionic radii also decrease in this same order. To explain these results, a partial covalent character may be ascribed to the bonding in the transuranium complex ions. It is shown that a reasonable structure for such covalent bonding involves hybridization of the 5f orbitals in the actinide elements.

Download or read book Modern Alchemy Selected Papers Of Glenn T Seaborg written by Glenn T Seaborg and published by World Scientific. This book was released on 1994-05-20 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: During his distinguished career spanning more than 50 years, Nobel laureate (Chemistry) Glenn T Seaborg published over 500 works. This volume puts together about 100 of his selected papers. The papers are divided into five categories. Category I consists of papers which detail the discovery of 10 transuranium elements and numerous heavy isotopes of special importance. Category II papers describe the discovery of a number of isotopes which became the workhorses of nuclear medicine or found other applications. Papers in Category III describe how the chemical properties of transuranium elements were originally determined, how chemistry is applied in nuclear sciences, and other chemical investigations, including early work done with the great chemist G N Lewis. Papers in Category IV cover radioactive decay chains and nuclear systematics. Lastly, papers in Category V illustrate how the powerful methods of chemistry are used to explain nuclear reactions in low, intermediate and high energy nuclear physics.
Download or read book Ion Exchange and Solvent Extraction written by Bruce A Moyer and published by CRC Press. This book was released on 2019-06-18 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume will capture transformational changes in both the chemistry and engineering side of solvent extraction, creating new directions and deepening our understanding of the structure and dynamics of liquid-liquid systems from the molecular- to nano- to meso- to bulk-scale. Reviews will cover advances in microfluidics, new tools for understanding the structure and dynamics of the liquid-liquid interface, ionic liquids in liquid-liquid extraction, molecular dynamics to visualize interactions in the solvent phase, liquid-liquid electrochemistry to interrogate the energetics of interfacial transport and complexation, design of new extractants, and the streamlining of process applications.

Download or read book Cation Exchange Behavior of Lanthanides and Trivalent Actinides in Ethanol hydrochloric Acid written by S. F. Marsh and published by . This book was released on 1974 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cation exchange in various organic solvent-hydrochloric acid media was studied for separating microgram levels of fission products from trivalent actinides. Ethanol provided the largest group separation factors. With either conventional or macroporous resins, equilibrations were too slow for useful column operation. The slow equilibration was caused by slow diffusion of the inorganic ions within the resin beads. A pellicular ion exchange resin, consisting of silica beads with a thin shell of resin, gave rapid and complete lanthamide-trivalent actinide separations.
