Liquid Membranes

This interesting work extensively describes newer applications of liquid membrane systems which contain molecular and/or ion recognizing carrier compounds and the related characteristic membrane materials. This volume focuses on the current knowledge about chemistry, biology and related technology of liquid membranes. It reviews the most recent advances in design and characteristics of synthetic liquid membrane transport. Additionally, this fascinating reference discusses up-to-date topics in the analytical and separation science, plus biomimetic membrane technology. Because this book is presented in a compact, understandable format, readers can start from biological cell membranes, then net aspects of host-guest chemistry for effective recognition of ions and molecules, followed by its application for artificial sensors-such as neuro-systems, functionalized new detergents, mechanochemical systems, and separation chemistry. This publication is ideal for graduate-level students and will stimulate university and industry researchers.

Liquid Membranes: Principles and Applications in Chemical Separations and Wastewater Treatment discusses the principles and applications of the liquid membrane (LM) separation processes in organic and inorganic chemistry, analytical chemistry, biochemistry, biomedical engineering, gas separation, and wastewater treatment. It presents updated, useful, and systematized information on new LM separation technologies, along with new developments in the field. It provides an overview of LMs and LM processes, and it examines the mechanisms and kinetics of carrier-facilitated transport through LMs. It also discusses active transport, driven by oxidation-reduction, catalytic, and bioconversion reactions on the LM interfaces; modifications of supported LMs; bulk aqueous hybrid LM processes with water-soluble carriers; emulsion LMs and their applications; and progress in LM science and engineering. This book will be of value to students and young researchers who are new to separation science and technology, as well as to scientists and engineers involved in the research and development of separation technologies, LM separations, and membrane reactors. Provides comprehensive knowledge-based information on the principles and applications of a variety of liquid membrane separation processes Contains a critical analysis of new technologies published in the last 15 years

The applications of solvent extraction (SX) and liquid membranes (LM) span chemistry, metallurgy, hydrometallurgy, chemical/mineral processing, and waste treatment—making it difficult to find a single resource that encompasses fundamentals as well as advanced applications. Solvent Extraction and Liquid Membranes: Fundamentals and Applications in New Materials draws together a diverse group of internationally recognized experts to highlight key scientific and technological aspects of solvent extraction that are critical to future work in the field. The first chapters identify relevant thermodynamics, kinetics, and interfacial behavior principles and introduce methods for calculating extraction equilibria and kinetic parameters. The next chapters focus on engineering and technological aspects of various industrial processes and plant applications, including optimization and modeling tools and calculations. The final chapters examine new materials for metal extraction and separations, covering preparation and application processes for organic and inorganic sorbents, solid polymeric extractants, and solvent impregnated resins. Solvent Extraction and Liquid Membranes offers a comprehensive review of the most important principles, calculations, and procedures involved in this widely applicable separation technique. The book’s pedagogical approach will benefit students and researchers in the field as well as working scientists and engineers who wish to apply solvent extraction to their own applications.

The plan of this book is to present the relevant thermodynamic features of fluid mixtures in contact with semipermeable barriers, then to apply this information in deriving the design requirements of individual membrane separation processes. The membranes, by this approach, are introduced by way of the mass transport and selectivity demands which they are to meet. This book gives a survey, in systematic order, of the terms and concepts by which barrier separations operate.

This book introduces recent developments of membrane technologies applied to gas and water treatments, energy processes and environmental issues. Novel knowledge and mechanisms on membrane fabrication and usage in energy, chemical, and environmental engineering are detailed in 12 book chapters from France, UK, Spain, China, Nigeria, Iran and Pakistan. The information in this book will be useful for engineers, students, and experts in these fields.
