Book Description
This volume addresses a broad spectrum of the environmental issues surrounding organic bromine and iodine compounds. It covers their partition among the environmental compartments and the potential for their long-range dissemination. The important issue of their atmospheric chemistry is discussed in detail in the context of ozone depletion and global warming, and the significant difference between the reactions of methyl bromide and methyl iodide are underscored. The mammalian toxicity is discussed and the mechanisms of the degradation and transformation of organic bromine and iodine compounds addressed. There has been considerable interest in naturally occurring metabolites in the current debate on the fate and partition of methyl bromide that is an important fungicide and is produced in substantial quantities as a metabolite of marine algae. The possible natural occurrence of diphenyl ethers that are used as flame retardants have also been raised. A discussion is given on plausible mechanisms for the biosynthesis of representative organic bromine and organic iodine metabolites. Reaction pathways are illustrated throughout and comprehensive references are given.

The Chemistry of Chlorine, Bromine, Iodine and Astatine
Author: A. J. Downs
Publisher: Elsevier
ISBN: 1483158322
Category : Science
Languages : en
Pages : 509
Book Description
The Chemistry of Chlorine, Bromine, Iodine and Astatine is a special edition that contains selected sections and addresses the needs of specialists in their respective fields. The text describes the general atomic properties of non-metals, particularly the halogens, as being the perfect series to study, both in physical and chemical terms. The book explains that the combination of the atomic properties implies excellent electronegativity values for the halogen atoms. The text also cites some behavior characteristics of halogens that are irregular, such as chlorine and bromine are similar but differ from fluorine on one side and iodine on the other. The book also compares the general methods of producing chlorine, bromine, or iodine by 1) oxidation of halide derivatives or 2) reduction of compounds of the halogens in positive oxidation states. The text then reviews the application of a complex valence theory that raises difficult questions about the bonding in halogen-oxygen molecules. The book also explains the biological behavior of astatine that accumulates in the liver or in the thyroid gland depending on the method of administration either as a radiocolloid or as a true solution. The book is suitable for molecular biologists and researchers, molecular chemists, and medical researchers.

Chemical Poems

Pages : 0
Book Description
Poetry. "How many gorillas must disappear, so that we can talk comfortably on our cell phones? Tantalum, the chemical element number 73, abundant in African ores, gives us the answer. It makes its confession, along with other ingredients of the world, under the researching pen of Mario Markus. This work removes the threshold between the visible and the invisible, indifference and surprise, science and poetry. The chemical elements are more than gadgets of the universe: they are some of the wonderful responses that shape our bodies and fill our spirits with a lasting plenitude. Markus' frank and rich poetry shows this to us as he relates the elements to wine and pencils, music and lamps, mirrors and the courtship of butterflies. From verse to verse, the periodic table becomes no longer a rigid information scheme, but a window into creation and its most precious truth, which is life."—Fl via Alvares Ganem, Brazilian poet

Halogens and Noble Gases, Second Edition
Author: Monica Halka
Publisher: Infobase Holdings, Inc
ISBN: 1438182090
Category : Science
Languages : en
Pages : 136
Book Description
In spite of their adjacency in the periodic table, halogens and nonmetals have very different properties. Halogens are among the most chemically reactive elements in the periodic table, exhibiting a diverse chemistry in terms of the large numbers of compounds they can form. On the other hand, noble gases are the least chemically reactive elements. In fact, before the 1960s, chemists referred to these elements as inert gases, because it was believed that they exhibited no chemistry whatsoever. Providing the basics of these elements, including their role in history and some of the important scientists involved in their discovery, this newly updated, full-color resource features up-to-date scientific understanding in a clear and accessible format. Halogens and Noble Gases, Second Edition examines the ways humans use halogens and noble gases and the resulting benefits and challenges to society, health, and the environment. Fluorine, chlorine, bromine, iodine, helium, and krypton are covered in this eBook, along with the fundamentals of chemistry and physics as well as possible future developments in halogen and noble gas science and its applications.

Author: Z. Marczenko
Publisher: Elsevier
ISBN: 0080541089
Category : Science
Languages : en
Pages : 526
Book Description
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.
