About this book
Adsorption of Metals by Geomedia serves as a needed resource for this topic which has received much attention during the past 15 years. The book provides an in-depth review of the field, followed by numerous chapters that document the current status of adsorption research for a variety of metals by geomedia ranging from individual minerals to sediments and soils. Adsorption mechanisms are detailed and precipitation is presented as a distinct sorption process. Virtually all factors affecting the extent of metal adsorption are examined, including the effects of selected anions, competition among metals, pH, metal concentration, loading, variable metal adsorption capacity, ionic strength, hydrogen exchange and stoichiometry, and solids concentration. A variety of adsorption models are briefly presented and some are used to extend laboratory studies to field sites. The book is comprised of a collection of papers contributed by leading investigators from Canada, France, the Netherlands, the United Kingdom and the US. It includes a wide-ranging review of the status of adsorption research and a prospectus on future research. It details all known factors affecting the extent of adsorption. It covers basic adsorption equations and interrelationships. It clearly documents experimental procedures. It presents adsorption data for eleven metals and three other elements. It uses normalization to greatly reduce apparent variability among absorbents. It provides extensive literature citations and a comprehensive index.

Biography
Dr. Everett Jenne has served on the committee of the National Academy of Sciences and as president of the Society for Environmental Geochemistry and Health, and has also held adjunct appointments at the University of Washington and Stanford University. Dr. Jenne is best known for his role in establishing the major role of hydrous oxides, particularly iron, as controls on the solute concentration of transition series metals and other trace elements in soils and sediments and for his efforts in the development and application of geochemical models competent to handle speciation, adsorption, solubility, and mass transfer of major and minor trace elements, including radionuclides, in a wide range of waters. Prior to his retirement in 1995, Dr. Jenne was involved for a number of years in geochemical and acid-rain related watershed modeling at Pacific Northwest National Laboratory. Simultaneously, he undertook a systematic review of adsorption/desorption data. During this period he also became interested of the rates of dissolution of Al and Si oxides, particularly the amorphic varieties, under both acidic and basic conditions.
