This book was released on 2000-10-18 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectrophotometry enables one to determine, with good precision and sensitivity, almost all the elements present in small and trace quantities of any material. The method is particularly useful in the determination of non-metals and allows the determination elements in a large range of concentrations (from single % to low ppm levels) in various materials. In Separation, Preconcentration and Spectrophotometry in Inorganic Analysis, much attention has been paid to separation and preconcentration methods, since they play an essential role in increasing the selectivity and sensitivity of spectrophotometric methods. Separation and preconcentration methods have also been utilised in other determination techniques. Spectrophotometric methods which are widely used for the determination of the elements in a large variety of inorganic materials are presented in the book whilst separation and preconcentration procedures combined with spectrophotometry are also described. This book contains recent advances in spectrophotometry, detailed discussion of the instrumentation, and the techniques and reagents used for spectrophotometric determination of elements in a wide range of materials as well as a detailed discussion of separation and preconcentration procedures that precede the spectrophotometric detection.

Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Manganese, Technetium and Rhenium is a three-chapter book that discusses the composition, structure, properties, and change of manganese, technetium, and rhenium. The first chapter in this particular book is the 37th chapter of the volume of a series, which focuses on manganese. The history, occurrence, metallurgy, uses, and chemistry of manganese are specifically discussed in this chapter. The compounds of manganese are also presented. This chapter is followed by a chapter on the chemistry of technetium, including its discovery, isolation, and compounds. The last chapter is devoted to rhenium, discussing its discovery, isolation, compounds, and physical and chemical properties. This book will be invaluable to chemistry students and practitioners, especially those interested in the elements featured in this release.

Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Manganese, Technetium and Rhenium deals with the chemistry of manganese, technetium, and rhenium and covers topics ranging from the occurrence and metallurgy of all three elements to their properties and compounds. Among the compounds considered are manganese halides, cyanides, and oxides as well as carbonyls and organometallic compounds, thiocyanate complexes, and chalcogenides. This volume is divided into three sections and opens with an overview of the history and occurrence of manganese, along with its metallurgy, uses, and properties. A variety of manganese compounds are examined, including halides and cyanides, sulfides and selenides, tellurides and borates, and nitrites and nitrates. The next two sections focus on technetium and rhenium, their discovery, isolation, and general properties. Compounds of both elements are described, including hydridic compounds, cyanide and thiocyanate complexes, and oxoacids and salts. Perrhenic acid and the perrhenates are also discussed, together with chalcogenides and refractory compounds, carbonyls, and organometallic derivatives. This book will be a valuable source of information for inorganic chemists.
