Over the past several decades, the theme of supramolecular chemistry (SC) has permeated nearly all aspects of chemical endeavor. Not surprisingly, it has also pervaded the field of solvent extraction (SX), inspiring the framework for this volume of Ion Exchange and Solvent Extraction. In addition, tools for studying aggregation have grown increasingly sophisticated, leading to a greater understanding of what we now recognize as SC phenomena in SX. Volume 21, Supramolecular Aspects of Solvent Extraction identifies how supramolecular behavior occurs and is studied in the context of SX and how SC is influencing the direction of SX. With contributions by internationally recognized specialists from different fields, this volume examines how principles of SC are being used in advancing the design of new highly selective SX systems and for understanding aggregation phenomena in SX systems. The book begins with a discussion of the nature and definition of SC and its general use in the design of novel SX reagents. Chapter 2 expands the subject of ion-pair recognition to introduce outer-sphere recognition of metal complexes. Chapter 3 reviews the literature on calixarenes as extraction reagents for metal ions. Chapter 4 extends the utility of this chemistry, describing the use of calixarenes for the extraction of biomolecules. Chapter 5 examines the liquid–liquid interface as an expression of supramolecular phenomena in SX, reviewing interfacial aggregation in model two-phase systems and metal extraction systems. The final chapter explores the problem of aggregation in SX, the historical attempts to understand it, and recent progress that has been made in addressing the issue.

Despite the central role anionic species have been shown to play in both mineralogical and biological processes, until now there have been no comprehensive references dealing exclusively with anionic coordination chemistry. Written by a group comprising pioneering researchers from the United States and Europe, Supramolecular Chemistry of Anions covers all theoretical and practical aspects of anion complexation, from thermodynamics and structure to catalysis and various applications. The authors begin with the 1967 discovery of halide inclusion by bicyclic diammonium receptors and trace the development of anion coordination chemistry through the most recent developments in the field. Topics covered in detail include: * Pre-supramolecular anion chemistry * Natural and artificial molecules that can act as anion receptors * Preorganization and chemical design * Structural, thermodynamic, electrochemical, and photochemical aspects of anion coordination * Computer methods for receptor design and multiple host-guest relations * Anion receptor catalysis and molecular recognition and transformation of nucleotides Supramolecular Chemistry of Anions is a valuable professional resource for organic and inorganic chemists, analytical chemists, biotechnologists, pharmaceutical scientists, and environmental chemists. It also serves as an excellent graduate-level text for students of molecular recognition, catalysis, and biomimetic chemistry.

Metal ion separation and preconcentration constitute the pivotal step in numerous analytical, purification, and waste treatment processes. Increasing environmental regulations and growing economic incentives imply that separation science will be essential to the future of industrial processing. This volume offers a broad perspective of advances in the field while also including up-to-date work in a number of specialized areas. It begins with an overview which describes the objectives the book, summarizes each chapter, and presents some immediate challenges for the future. Two review chapters then address the status of metal ion separations in nuclear energy and defense-related programs. These are followed by twenty chapters covering a range of topics, including aqueous phases in separations, extractant design and synthesis, solvent extraction, solid-liquid distribution, separations using membranes, centrifugal partition and countercurrent chromatography, and supercritical fluid extraction systems. Together the essays provide a fine balance of fundamental and applied research, making the book invaluable for both novice and experienced practitioners.

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
