Surface Complexation Modeling: Gibbsite
"Whether interested in making practical thermodynamic calculations, or in reflecting on the fundamental nature of the interactions at interfaces, we should be thankful to Athanasios Karamalidis and David Dzombak for this new opus."
An important guide to the theory and practical application of surface complexation modeling for metal ion sorption on gibbsite
This insightful and pioneering work is a state-of-the-art, and practical treatise of surface complexation modeling of metal ion sorption on an important hydrous aluminum oxide—gibbsite—the most common form of aluminum oxide found in nature and one of the most abundant minerals in soils, sediments, and natural water.
Providing a synopsis of aluminum oxide forms and a clearly defined nomenclature for this class of minerals, Surface Complexation Modeling: Gibbsite uses the generalized two-layer surface complexation model, and demonstrates how to conduct mechanistic yet practical modeling of the sorption of metal ions and other inorganic species on hydrous metal oxides. Building on and extending to gibbsite the classic related work on hydrous ferric oxide by Dzombak and Morel, published in 1990, this book:
By bringing together and synthesizing available data and modeling methods for sorption on gibbsite, the authors present tools that will aid the study of the surface chemistry of this highly prolific, and extremely important, mineral, and will facilitate the practical application of surface complexation modeling.
