A complete and up-to-date presentation of the fundamental theoretical principles and many applications of solvent extraction, this enhanced Solvent Extraction Principles and Practice, Second Edition includes new coverage of the recent developments in solvent extraction processes, the use of solvent extraction in analytical applications and waste re
The main challenge in modern solvent extraction separation is that most techniques are mainly empirical, specific and particular for narrow fields of practice and require a large degree of experimentation. This concise and modern book provides a complete overview of both solvent extraction separation techniques and the novel and unified competitive complexation/solvation theory. This novel and unified technique presented in the book provides a key for a preliminary quantitative prediction of suitable extraction systems without experimentation, thus saving researchers time and resources. Analyzes and compares both classical and new competitive models and techniques Offers a novel and unified competitive complexation / solvation theory that permits researchers to standardize some parameters, which decreases the need for experimentation at R&D Presents examples of applications in multiple disciplines such as chemical, biochemical, radiochemical, pharmaceutical and analytical separation Written by an outstanding scientist who is prolific in the field of separation science
The Solvent Extraction of Metal Chelates is a comprehensive account of the solvent extraction (liquid-liquid extraction) of metal chelate complexes. Topics covered include the composition and stability of metal chelates; analytical applications of the solvent extraction of metal chelates; and selective extraction procedures for metals. A theoretical treatment of the solvent extraction of metal chelates is also given. This book is comprised of six chapters and begins with an overview of solvent extraction and how it can be used to solve important theoretical problems concerning the composition and stability of soluble and insoluble metal complexes. The next chapter examines the composition and stability of metal chelates based on the assumption that only uncharged complexes are dissolved and extracted by the organic solvents. A theory of the solvent extraction of metal chelates is then described, paying particular attention to a variety of factors that influence the extraction of metal chelates, including acidity, solubility and instability of the metal chelate, and organic solvent. Some analytical applications of the solvent extraction of metal chelates are also considered. The last two chapters deal with systems and selective extraction procedures for metals. This monograph will be of particular value to inorganic and analytical chemists.

Written by recognized experts in their respective fields, it serves as a one-stop reference for those who need to know which technique to choose for liquid phase extraction. Used in conjunction with a similar release, Solid Phase Extraction, it allows users to master this crucial aspect of sample preparation. - Defines the current state-of-the-art in extraction techniques and the methods and procedures for implementing them in laboratory practice - Includes extensive referencing that facilitates the identification of key information - Aimed at both entry-level scientists and those who want to explore new techniques and methods
This volume will capture transformational changes in both the chemistry and engineering side of solvent extraction, creating new directions and deepening our understanding of the structure and dynamics of liquid-liquid systems from the molecular- to nano- to meso- to bulk-scale. Reviews will cover advances in microfluidics, new tools for understanding the structure and dynamics of the liquid-liquid interface, ionic liquids in liquid-liquid extraction, molecular dynamics to visualize interactions in the solvent phase, liquid-liquid electrochemistry to interrogate the energetics of interfacial transport and complexation, design of new extractants, and the streamlining of process applications.
Solvent Extraction in Biotechnology deals with the reco- very and purification of primary and secondary metabolites by solvent extraction. In the first part the reaction engineering principles: definitions, thermodynamic fundamentals, and system models, the kinetics of mass transfer between two phases without and with chemical reaction as well as extraction equipment, which are important for downstream processing in biotechnology, are considered in detail. The special part of the book describes the recovery of low-molecular metabolites: alcohols, acids and antibiotics with organic solvents, carrier-modifier-solvent systems, supercritical gases as well as with liquid membrane techniques. Several practical examples are given for the recovery of different metabolites as well as for the calculation of the extraction processes necessary for equipment design. Besides solvent extraction, novel separation techniques with liquid membrane, microemulsion and reversed micelles are also presented. This book will introduce the biochemical engineer and process engineer to the recovery of products from complex cultivation broths by modern techniques of solvent extraction and help them with process design.
Solvent Extraction in Flame Spectroscopic Analysis provides an introductory discussion on the technique of solvent extraction in flame spectrometry. The book is comprised of six chapters the cover the various aspects and applications of solvent extraction. The text first covers the role of solvent extraction in flame spectrometric analysis, and then proceeds to describing the solvent suitable for flame spectrometry. Next, the book discusses the theoretical and practical aspects of the solvent extraction technique. The text also covers the application of the technique on various elements. The book will be of great use to researchers and professionals who require a good understanding of the various techniques in spectrometry.
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.

The growth in the world's nuclear industry, motivated by peaking world oil supplies, concerns about the greenhouse effect, and domestic needs for energy independence, has resulted in a heightened focus on the need for next-generation nuclear fuel-cycle technologies. Ion Exchange and Solvent Extraction: A Series of Advances, Volume 19 provides a com
The aim of this book is to present the current state of the art of extracting natural products with near-critical solvents and to view the possibilities of further extensions of the technique. Relevant background theory is given but does not dominate the book. Carbon dioxide is the near-critical solvent used in most recent applications and inevitably receives prominence. In addition to general descriptions and reviews, the book contains three chapters by indus trial practitioners who describe in detail the operation of their processes and discuss the market for their products. Sections on the design of the pressure vessels and pumps required in these processes and on the acquisition of the data required for design are included. The costing of the processes is also discussed. There is good scope for combining a near-critical extraction step with other process steps in which the properties of near-critical solvents are utilised, for example as a reaction or crystallisation medium and a chapter is devoted to these important aspects. It is hoped that the work will be found to contain a great deal of specific information of use to those already familiar with this field. However the style of presentation and content is such that it will also be useful as an introduction. In particular it will be helpful to those wondering if this form of separation method has anything to offer for them, whether they are engineers, chemists or managers in industry, or in academic or research institutions.
