Description
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.
