Book Preconcentration Techniques For Trace Elements

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.

Book Mass spectrometric Determination of Trace Elements in Aqueous Media Without Preconcentration

Download or read book Mass spectrometric Determination of Trace Elements in Aqueous Media Without Preconcentration written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Feasibility of using a low pressure glow discharge as an ion source for the mass spectrometric determination of trace elements in aqueous media was investigated. A cryogenically cooled hollow cathode ion source was developed to analyze aqueous samples without external preconcentration. Aqueous solutions containing seventy elements were analyzed and the detection limits, sensitivity factors, and linear regression correlation coefficients were determined. A standard test solution of trace elements in water was analyzed and the concentrations of trace elements were calculated using the sensitivity factors determined previously. The results compared favorably within the error limits predicted by the semiquantitative survey methods used. Tap water and natural lake water samples were examined and minimal interference effects due to organic compounds and biological compounds were noted. A research ion optical system (RIOS) was developed as a flexible mass analyzer for the development of new ion sources. The RIOS is a double focussing mass analyzer designed utilizing the Mattauch-Herzog geometry with externally adjustable slit assemblies.

Book Analytical Techniques for Trace Elements in Geochemical Exploration

Download or read book Analytical Techniques for Trace Elements in Geochemical Exploration written by Raghaw Saran and published by Royal Society of Chemistry. This book was released on 2022-12-07 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace element analysis plays a prominent role in various fields, from mineralogy and geology to semiconductor manufacture and foods. In geochemical exploration, the analysis of trace elements assumes high significance due to the multifaceted role played by them. The analyte is at the detection limit of many instrumental techniques. This makes their determination difficult This book covers a wide spectrum of destructive and non-destructive analytical techniques and recent developments in them used all over the world, including developing countries, for quantitation of trace elements. With revolutionary progress in the last three to four decades in analytical techniques, several ICP-based techniques like ICP-OES and ICP-MS and other nuclear analytical techniques have enabled determination of trace elements at the ppb level. However, these methods require expensive instrumentation and cannot be made available everywhere. The quality of analytical data is dependent on valid reference standards. The book contains detailed sample preparation in varying matrices and an important chapter on statistical treatment of analytical data for the purpose of quality control and quality assurance. Pulling together, the book, containing the work carried out by the author’s group in India, will be useful to analysts involved in geochemical explorations.

Book Instrumental Multi Element Chemical Analysis

Download or read book Instrumental Multi Element Chemical Analysis written by Z.B. Alfassi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of materials containing several elements used to be a difficult problem for analytical chemists, so a well established sequence of wet chemical qualitative tests were performed to ensure each element was detected. Quantitative tests could then be carried out on the sample, according to the range of elements present. Most analytical chemists were very familiar with these techniques, having been taugth them from a very early stage in their education and careers. The analytical chemist can now call on a range of specialist instrumental techniques which can detect the presence of many elements, often simultaneously, and often quantitatively, providing rapid results on samples which, in the past, could take days. The drawback is that the instruments tend to be expensive, suited to particular sample types or matrices and complex in both setting up and in the interpretation of results. Furthermore the general analytical chemist may have access and familiarity with only one or two methods. Written by an international team of contributors, each experts in their particular fields, this book familiarizes analytical chemists with the range of elemental analysis techniquers, to enable them to specify the most appropriate test for any given sample. In addition, it contains important chapters on sample preparation and quality control, essential elements in obtaining accurate and reliable analytical results. As such, this book will be essential reading for all analytical chemists. The techniques of elemental analysis are important in many other disciplines, so the book will be of particular interest to those commissioning a wide range of analytical measurements, such as chemists, geologists, environmental scientists and biologists. The breadth and depth of coverage will also make the book very useful for advanced students.

Book Separation Preconcentration and Spectrophotometry in Inorganic Analysis

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.
