The purpose of this book is to present in a monographic and systematised form a review of all the literature devoted to polyurethane-based polymeric sorbents in separation chemistry. The primary types of sorbents dealt with are polyurethane foams and open-pore polyurethanes. The structure of the monograph follows this dichotomy. A book of this nature should stimulate thinking and incite its reader to consult the original literature. It will, however, not make such a consultation superfluous. A fair amount of the results described in this monograph constitute the main activity of investigation which took place in the authors laboratories during the past decade.

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.

This book will provide the most recent knowledge and advances in Sample Preparation Techniques for Separation Science. Everyone working in a laboratory must be familiar with the basis of these technologies, and they often involve elaborate and time-consuming procedures that can take up to 80% of the total analysis time. Sample preparation is an essential step in most of the analytical methods for environmental and biomedical analysis, since the target analytes are often not detected in their in-situ forms, or the results are distorted by interfering species. In the past decade, modern sample preparation techniques have aimed to comply with green analytical chemistry principles, leading to simplification, miniaturization, easy manipulation of the analytical devices, low costs, strong reduction or absence of toxic organic solvents, as well as low sample volume requirements. Modern Sample Preparation Approaches for Separation Science also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and forensic sciences.

Chromatography approaches are widely used in various life science applications. Since its invention by the Russian botanist Mikhail S. Tsvet in 1901, chromatography has increasingly developed into an invaluable laboratory tool for the separation and identification of chemical components. It outperforms older techniques (such as crystallization, solvent extraction, and distillation) by offering unequaled resolving power and the possibility of lowering detection limits to below nanogram levels. To further improve chromatographic methods, however, the use of chemometrics is advisable as an economical alternative to resolve any problematic situations in analysis. This book intends to provide the readers with an up-to-date application of chemometrics and data analysis to different types of chromatographic methods.

Separation of chemical species is a gate to final success of synthesis and preparation of compounds in pure and defined state. Variability of natural and artificial mixtures to be treated is enormous. Task of chemistry is to separate components of homogeneous mixtures (the gaseous and liquid solutions). The book concentrates on understanding the basic philosophies of both equilibrium and nonequilibrium chemical thermodynamics and engineering performance that lay in principle of separation technique such as distillation, crystallization, centrifugation, sorption, membrane separations, chromatography, and liquid-liquid extraction. Specific phenomena connected with photochemical separation, isotope composition, and radioactivity are discussed as well. The book is written for advanced students of chemistry having the knowledge of physical chemistry. Calculation examples are based on the international system of units. Unique list of over 1,300 full references covers scientific literature of the eighteenth to the twenty-first centuries.
