Download or read book Separation Preconcentration and Spectrophotometry in Inorganic Analysis written by Z. Marczenko and published by Elsevier. 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 Preconcentration Techniques For Trace Elements written by Zeev Alfassi and published by CRC Press. This book was released on 1991-12-07 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate determination of trace elements is critical in various fields of science and technology. Direct measurement of trace elements in samples with complex matrices is often impractical, either due to analytical sensitivity limitations or matrix interferences. Preconcentration procedures are generally needed to eliminate matrix interferences and/or enrich minute amounts of analytes to a level for reliable measurements. Preconcentration Techniques for Trace Elements provides up-to-date information on various preconcentration techniques and detailed discussions regarding such topics as the dissolution of matrices, coprecipitation, solvent extraction, electrochemical means, ion exchange, sorption, chromatographic methods, flotation, membranes, volatization, polymer foam sorbents, fire assay, isotachophoresis, and filter papers. This comprehensive volume, featuring contributions from 21 experts from nine countries, will provide valuable reference material for all scientists and technicians dealing with trace analysis of real-world samples.

It drew presenters from Australia, the Czech Republic, France, Germany, Japan, South Africa, Thailand, the United Kingdom, and the United States. Separations constitute an integral part of chemical industry. Chemical products typically originate in resources that must be concentrated and purified, chemically transformed, and subjected to fmal purification. Effluent streams from the processes must be treated to recycle reusable components and to remove environmentally harmful species. Some industrial processes are devoted to environmental cleanup after pollution has occurred. In addition, many analytical methods require a separation for preconcentration, or a separation may be an inherent part of the analysis itself. Micro separations occurring at membranes or interfaces are also related phenomena employed for ion sensing. Many species targeted for separation are naturally anionic. Although the standard separations techniques ofextraction, ion exchange, adsorption, precipitation, etc.
