Advanced Separations by Specialized Sorbents opens a new window into sorbent materials, presenting fundamental principles for their syntheses and adsorption properties. The book presents advanced techniques used to create specialized sorbents with a wide range of functions that can be used to enhance the separation and/or purification of useful bioactive compounds, heavy metals, dyes, and other substances. It discusses the most recent developments in the field of separation processes, covering specialized sorbents such as monolith cryogels, composite hydrogels, metal-impregnated ion exchangers, and molecularly imprinted polymers. The book provides a comprehensive discussion of the selectivity in separation processes by composite materials based on synthetic polymers/biopolymers and inorganic particles. It is a comprehensive resource for academic and research scientists as well as students interested in the preparation, characterization, and application of specialized sorbents.

Separation processes-or processes that use physical, chemical, or electrical forces to isolate or concentrate selected constituents of a mixture-are essential to the chemical, petroleum refining, and materials processing industries. In this volume, an expert panel reviews the separation process needs of seven industries and identifies technologies that hold promise for meeting these needs, as well as key technologies that could enable separations. In addition, the book recommends criteria for the selection of separations research projects for the Department of Energy's Office of Industrial Technology.

Stable, safe, secure and readily available water supply is one of the key factors in ensuring a good level of the public health and a stable society. Scientific assessments show that about 80 % of diseases and one-third of the total death toll in the developing countries are caused by the low quality of the drinking water. Other countries are also suffering from water shortages and insufficient quality of the drinking water. Many rivers in Europe and in other parts of the world are significantly polluted by insufficiently treated or untreated wastewater discharge. This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Lviv, Ukraine, and addressed recent advances in water supply and wastewater treatment as a prerequisite for a safer society and environment. The contributions critically assess the existing knowledge on urban water management and provide an overview of the current water management issues, especially in the countries in transition in Central and Eastern Europe and in the Mediterranean Dialogue countries.

Thin-layer chromatography (TLC) has become a common and much favoured separation technique in laboratories in widely varied fields in recent years. Much of the credit for the introduction of this technique into analytical practice at the l 2 end of the 1950s is due to E. Stahl • • This method is simple and is characterized by high separation ability and sufficient sensitivity3; however, some analysts feel that it has passed the peak in its development and will gradually be replaced by the more modem high-performance liquid chromatography (HPLC). This is undoubtedly a very important analytical technique utilizing the specific separa tion properties of a large number of sorbents and the possibility of regulating 4 the flow-rate of the mobile phase by adjusting the pressure • Standardization of the experimental conditions is simpler in HPLC than in TLC, where the activity of the sorbent and flow-rate of the eitlent in the thin layer depend markedly on the relative humidity of the laboratory atmosphere and on the composition of the gaseous phase in the elution chamber. In addition, systems for quantitative detection of the separated ~ones are better developed for HPLC than for classical TLC, where, until recently, cumbersome and often even insufficiently reproducible chemical or gravimetric analysis of the extracts of scraped-off spots or densitometry of the separated zones, located first by pyrolysis or reaction s with suitable detection agents, were the predominant determination methods .

Chemometrics uses advanced mathematical and statistical algorithms to provide maximum chemical information by analyzing chemical data, and obtain knowledge of chemical systems. Chemometrics significantly extends the possibilities of chromatography and with the technological advances of the personal computer and continuous development of open-source software, many laboratories are interested in incorporating chemometrics into their chromatographic methods. This book is an up-to-date reference that presents the most important information about each area of chemometrics used in chromatography, demonstrating its effective use when applied to a chromatographic separation.

Thin Layer Chromatography for Binding Media Analysis

In the study and conservation of art and artifacts, natural organic materials are frequently encountered in components such as coatings, binders, and adhesives. The identification of these materials is often crucial to the attempt to characterize the technologies employed by artists or craftspeople, understand the processes and causes of deterioration, and plan appropriate conservation treatments. Yet the limited resources of many conservation laboratories put many analysis techniques beyond their reach. Thin-layer chromatography can help fill this gap. The volume consists of a handbook, protocols, and guide to reference materials. The handbook serves as a primer for the basic application of thin-layer chromatography to the analysis of binding media, adhesives, and coatings found on cultural objects; the protocols provide step-by-step instructions for the laboratory procedures involved in typical analyses; and the guide to reference materials aids in the understanding of the types of materials and documentation needed for accurate analyses by thin-layer chromatography.
