Book Description
An ultraviolet spectrophotometric method for the determination of uranium has been developed which is based on the ultraviolet absorption of the complex of uranium(VI) with tris-(2-ethylhexyl)phosphine oxide. The complex is formed by extracting uranium(VI) from an aqueous 6M sodium nitrate solution in the pH range 2.5-3.0 into 0.1M solution of tris-(2-ethylhexyl)phosphine oxide (TEHPO) in an inert diluent, cyclohexane.

Book Description
This book provides an overview of the state of the art in pharmaceutical applications of UV-VIS spectroscopy. This book presents the fundamentals for the beginner and, for the expert, discusses both qualitative and quantitative analysis problems. Several chapters focus on the determination of drugs in various matrices, the coupling of chromatographic and spectrophotometric methods, and the problems associated with the use of chemical reactions prior to spectrophotometric measurements. The final chapter provides a survey of the spectrophotometric determination of the main families of drugs, emphasizing the achievements of the last decade.

Book Description
UV-Visible Spectrophotometry of Waters and Soils, Third Edition presents the latest information on the use of UV spectrophotometry for environmental quality monitoring. Using practical examples, the book illustrates how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique is one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (e.g., Nitrate, TOC) and simultaneously qualitative information on the global composition of waters and soils. This third edition presents current methods and applications for water quality monitoring, including recent works and developments. Writing from years of experience in the development and applications of UV systems and from scientific and technical works, the book's authors provide several useful examples that show the great interest of UV spectrophotometry for water and soil monitoring. At the end of the book, the UV spectra library of previous editions is updated with new chemicals of interest. - Broadens coverage from previous editions, including soils and sediments for the first time - Includes all new chapters on natural water and high frequency monitoring, agricultural soils, natural soils, and sediments, as well as updates in all other chapters - Provides a theoretical basis for further research in the field of spectra exploitation - Contains practical applications of this quick, simple and inexpensive technique

Book Description
UV-Visible Spectrophotometry of Water and Wastewater is the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples the reader is shown how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (eg. Nitrate, TOC), and simultaneously qualitative information on the global composition of water and its variation.* First electronic library of UV-spectra providing data readily available for researchers and users* Provides a theoretical basis for further research in the field of spectra exploitation* Contains helpful practical applications
