Bromine

Introduces the element of bromine and its compoinds, discussing its physical and chemical properties, where it is found, and how it is used.

Explores the element of Bromine and its uses.

What gives Tyrian purple dye its brilliant color--the element bromine (chemical symbol: Br). Bromine compounds were first extracted from a tropical sea snail in ancient times and used in purple dyes for fabrics. The color was sometimes called imperial or royal purple. This engaging narrative describes the discovery of bromine, its place on the periodic table, its similar and different characteristics with the other halogens in group 17, and its electron configuration. A thorough discussion of bromine ions, the process of steaming out in preparing pure bromine, and the various bromine compounds and their industrial uses are also included.

This book provides detailed information on the history, analysis and applications of chlorine and bromine isotope geochemistry. Chlorine and bromine are geochemically unique as they prefer to exist as single charged negative ions. For this reason isotope fractionation reflects mostly processes that are not related to changes in the redox state and this fractionation is generally modest. The book will describe the processes that are most easily detected using these isotopes. Also isotope variations, and processes that cause them, measured in oxidised species such as perchlorates and in organic molecules will be described in this book.

A multidisciplinary approach to research studies of sedimentary rocks and their constituents and the evolution of sedimentary basins, both ancient and modern.

This book presents a detailed technical overview of short- and long-term materials and design challenges to zinc/bromine flow battery advancement, the need for energy storage in the electrical grid and how these may be met with the Zn/Br system. Practical interdisciplinary pathways forward are identified via cross-comparison and comprehensive review of significant findings from more than 300 published works, with clear in-depth explanations spanning initial RFB development to state-of-the-art research in related systems. Promising strategies described include the use of modern electrochemical techniques to study and optimize physical processes occurring within the system during operation, improving zinc electroplating quality during the charge phase through the strategic use of organic additives, as well as identifying suitable catalysts to optimize the bromine/bromide redox couple. The primary focus is on research and development of novel materials in the areas of electrolyte formulation and multifunctional “smart” electrode surfaces to achieve a higher degree of control over processes at the electrode–electrolyte interface. The strategies suggested in this book are also highly adaptable for use in other similar flow battery systems, while the unique cross-comparative approach makes it a useful reference and source of new ideas for both new and established researchers in the field of energy storage and battery technology.

This report presents the results from an investigation of the emissions of dioxin-compounds that may occur from incineration of plastic waste containing brominated flame retardants (BFRs) together with waste from households and the commercial sector. The decomposition of BFRs was also investigated. The most common use for BFRs is in building materials, textiles and electronic supplies, e.g. TVs, PCs and photocopiers. In incineration plants with good combustion BFRs will decompose and form other brominated compounds, mainly hydrogen bromide (HBr). In addition, other brominated compounds will also be formed, in particular brominated organic compounds, such as dioxins where chlorine is fully or partly substituted by bromine (brominated and brominated/chlorinated dioxins). The project results presented in this report serve as a basis for authorities and the owners of incineration plants, to make decisions about whether, and under what conditions, this type of waste may be incinerated. The project was financed by the PA-group under the Nordic Council of Ministers.
