Adsorption of Metals by Geomedia II serves as a needed resource for this topic which has received much attention during the past 25 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. This is a compilation of 25 peer reviewed papers from among the 60+ platform and poster presentations of the symposium "Adsorption of Metals to Geomedia II" at the American Chemical Society (ACS) Meeting, March 27-29, 2006 in Atlanta, Georgia, USA. This symposium is a follow-up to the original held in 1996. * Learn the tools and techniques from leading academics and industry experts * One stop practical resource and guide for those in the field * Keep informed and up to date on all the latest advancements in technology

A central safety function of radioactive waste disposal repositories is the prevention or sufficient retardation of radionuclide migration to the biosphere. Performance assessment exercises in various countries, and for a range of disposal scenarios, have demonstrated that one of the most important processes providing this safety function is the sorption of radionuclides along potential migration paths beyond the engineered barriers.Thermodynamic sorption models (TSMs) are key for improving confidence in assumptions made about such radionuclide sorption when preparing a repository's safety case. This report presents guidelines for TSM development as well as their application in repository performance assessments. They will be of particular interest to the sorption modelling community and radionuclide migration modellers in developing safety cases for radioactive waste disposal.

Safe and effective management of nuclear waste provides a broad range of challenges for materials science. Waste processing, waste form and engineered barrier properties, interactions between engineered and geological systems, radiation effects, chemistry and transport of waste species, and long-term predictions of repository performance are just some of the scientific problems facing modern society. This book, the 22nd in a very successful series from MRS, offers an international and inter-disciplinary perspective on the issues, and features developments in both fundamental and applied areas. Topics include: development and characterization of ceramic waste forms; ceramic waste form corrosion; glass waste form processing; glass formulation, properties and structure; glass waste form corrosion; spent nuclear fuel; performance assessment; repository backfill; flow and transport; natural analogues; container corrosion; metal waste form corrosion; radionuclide speciation and solubility; radionuclide sorption; microbial effects; radiation effects; cement waste forms and waste treatment.

GEOTRAP is the OECD/NEA Project on Radionuclide Migration in Geologic, Heterogeneous Media carried out in the context of site evaluation and safety assessment of deep repository systems for long-lived radioactive waste. Retention of radionuclides within the geosphere for prolonged periods is an important safety function of deep geologic disposal concepts for radioactive waste. The extent to which retention processes can be relied upon in repository performance assessment depends upon the existence of well-established theoretical bases for the processes. It also depends on support for the opera.

The subject of water and solute transport in porous media is one of lhe most fascinating areas of science. Tremendous advances have been recently made in understanding lhe soil physical/chemical processes of water and solute transport/retention in soils. Recent emphasis includes water retention based on pore-scale modeling, flow in multiregions/multidomains, scaling and heterogeneity, prefractal networks, percolation models, numerical simulations, and cellular automata. Advances in experimental methods include confirrnation and measurement of adsorption phenomena at lhe clay mineral/aqueous solution interface, surface complexation modeling based on molecular spectroscopy and microscopy, and precipitation/dissolution. Interest in these topics led to lhe organization of a symposium on "Physical and chemical processes of water and solute transport/retention in soils" held in two sessions at lhe 1998 Soil Science Society of America Annual Meeting in Baltimore, Maryland, 18 to 22 Oct. 1998. This symposium was organized by Divisions S-1 and S-2.

Selected proceedings of the 7th International Conference on Wetland Systems for Water Pollution Control, held in Lake Buena Vista, Florida, USA, 11-16 November 2000. Wetlands are now considered as a widely applicable low-cost alternative for treating municipal, industrial and agricultural effluents. Increasing numbers of wetland projects have come into operation over the last decade, notably those in Florida. IWA's 7th Wetlands conference provided a forum for the synthesis and interpretation of the current status of treatment wetlands. The conference reflected the interdisciplinary nature of the topic, with a diversity of delegates from scientific and engineering disciplines contributing. It addressed research information on current understanding of treatment wetlands, and the need to transfer basic research information to managers involved in solving applied problems; and identified future directions for design and management of treatment wetlands. From a very large programme (of over 200 oral and poster presentations), 86 papers have been selected for these proceedings. As well as authoritative keynote presentations, there are papers on: phosphorus removal and transformations; nitrogen removal and transformations; pathogen removal; optimisation and modelling; ecological considerations; subsurface flow wetlands; surface flow wetlands; industrial wastewaters; agricultural wastewaters; and stormwater. They constitute an outstanding summary of our current knowledge of wetland systems in management of the water environment.
