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.

Physical Methods in Chemical Analysis, Volume IV focuses on the application of physical methods in chemical analysis, including dialysis, chromatography, electromagnetic separations, and thermal diffusion. The selection first offers information on dialysis and separations with molecular sieves and foams. Topics include membranes for dialysis, apparatus and techniques, application of molecular sieves to the problems of separation, adsorption measurements and techniques, and molecular sieve adsorbents. The text then elaborates on separations with foams and electromagnetic separations. The publication explains ion exchange and analytical applications of inclusion. Discussions focus on separations by ion-exchange chromatography, general properties of ion-exchange resins, ion exclusion, and methods and technical details. The publication then ponders on separation of gases and liquids by thermal diffusion and solvent extraction. The selection is highly recommended for readers interested in the application of physical methods in chemical analysis.

Due to increasing demand for potable and irrigation water, water suppliers have to use alternative resources. They either have to regenerate wastewater or deal with contaminated surface water. This book brings together the experiences of various experts in preparing of innovative materials that are selective for arsenic and chromium removal, and inventing some innovative processes to extract these elements from water. The book should be of high interest to engineers and decision-makers responsible for production and delivery of safe water. The book is divided into three parts. The first one shows the effect of arsenic and chromium ions on living organisms. The second one presents the studies on preparation of innovative materials with improved affinity towards arsenic as well as chromium. The third part shows the innovative methods for removal of these toxic elements, with special attention paid to chromatographic, membrane, and hybrid systems. The book is the first ever scientific work addressed to two most harmful elements appearing in water and provides a comprehensive review of materials and methods useful for making the water safe. The book discusses in detail the various fabrication techniques for sorbents and membranes that are now commercially available or appear in the development stage and will be commercialized in the next decades. Some of the technologies described in the third part will be implemented at the industrial scale in the future as well.
