Download or read book Metallurgical Processing and the Effect of Ethylenediaminetetra acetic Acid in Extraction and Separation of Rare earth Elements by Solvent Extraction with Di 2ethylhexyl Phosphoric Acid written by Sileymane Alpha Lo and published by . This book was released on 2012 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to determine the amenability to extraction of the rare earth elements (REE) and the effect of ethylene diamine tetra-acetic acid (EDTA), a chelating agent, on their separation in di-2ethylhexyl phosphoric acid (DEHPA) solvent extraction systems. To physically concentrate the ore, a screening process was used, and was successful in concentrating the rare earth elements hosted within the minerals in the fine size fractions, with higher grades in the minus 500 mesh (-25 microns) portion. The pre-concentrate was upgraded from a head grade of 13.8% to 19.1% REE using the simple screening process. Recoveries averaging 96% total rare earths were obtained in the leach tests with 20% hydrochloric acid at 90°C. Experiments of solvent extraction with DEHPA in kerosene were performed using the leachate produced in the leaching experiments. Different concentrations of EDTA were added to the aqueous phase prior to mixing with the organic. Addition of EDTA improves the percentage extraction and separation factors for some heavy rare-earth elements. Data from percent extraction and separation factors show noticeable sensitivity to concentrations of EDTA. It was observed that erbium (Er) and ytterbium (Yt) display the highest percent extractions of 84% and 92%, respectively.

Download or read book The Chemistry of the Actinide and Transactinide Elements 3rd ed Volumes 1 5 written by L.R. Morss and published by Springer Science & Business Media. This book was released on 2007-12-31 with total page 4059 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of the Actinide and Transactinide Elements is a contemporary and definitive compilation of chemical properties of all of the actinide elements, especially of the technologically important elements uranium and plutonium, as well as the transactinide elements. In addition to the comprehensive treatment of the chemical properties of each element, ion, and compound from atomic number 89 (actinium) through to 109 (meitnerium), this multi-volume work has specialized and definitive chapters on electronic theory, optical and laser fluorescence spectroscopy, X-ray absorption spectroscopy, organoactinide chemistry, thermodynamics, magnetic properties, the metals, coordination chemistry, separations, and trace analysis. Several chapters deal with environmental science, safe handling, and biological interactions of the actinide elements. The Editors invited teams of authors, who are active practitioners and recognized experts in their specialty, to write each chapter and have endeavoured to provide a balanced and insightful treatment of these fascinating elements at the frontier of the periodic table. Because the field has expanded with new spectroscopic techniques and environmental focus, the work encompasses five volumes, each of which groups chapters on related topics. All chapters represent the current state of research in the chemistry of these elements and related fields.
Download or read book Ion Exchange written by C E Harland and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion Exchange, 2nd Edition is a totally revised and updated version of the highly popular Monograph for Teachers, first published by The Royal Society of Chemistry in 1975. It covers the practical application of ion exchange and the synthesis of organic ion exchange resins, which have spanned nearly 60 years of development since the pioneering work of Adams and Holmes in 1935. This book covers the theory, development, and application in considerable detail and describes the history of development of ion exchange materials and the advances in their utilization in industrial processes. Key applications in such areas as water purification, hydrometallurgy, and chromatography are described and supported by chapters on the related scientific fundamentals governing equilibria and kinetics of ion exchange. Twenty-two experiments using inexpensive equipment are detailed, which not only complement a chapter dedicated to the characterization of organic exchangers, but also serve to illustrate several other pure and applied principles related to ion exchange phenomena. It is anticipated that the unique inclusion of experiments and the broad coverage of the whole text should appeal to a wide readership and offer particular relevance to practitioners in schools, colleges, and industry.
Download or read book Critical Survey of Stability Constants of EDTA Complexes written by G. Anderegg and published by Elsevier. This book was released on 2013-10-22 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical Survey of Stability Constants of EDTA Complexes focuses on the computations, values, and characteristics of stability constants. The book emphasizes that for a critical discussion of experimentally determined stability constants, it is important to consider the precision of the values that manifests the self-consistency of the constant, taking into consideration the random errors. The publication reviews the stability constants of metal complexes. The numerical calculations affirm the reactions and transformations of metal ions when exposed to varying conditions. The text also presents a list of enthalpies of reactions with (ethylenedinitrito)tetra-acetic acid (EDTA) obtained by direct calorimetric measurements. The book also notes that in order to identify reliable metal complex stability constants for a ligand, it is important to know the formation constants of protonated species. The text is a dependable reference for readers wanting to dig deeper into the stability constants of EDTA complexes.
