Surface Complexation Modeling (eBook)
John Wiley & Sons (Verlag)

surface complexation model, data treatment procedures, and
thermodynamic constants for sorption of metal cations and anions on
gibbsite, the most common form of aluminum oxide found in nature
and one of the most abundant minerals in soils, sediments, and
natural waters. The book provides a synopsis of aluminum oxide
forms and a clearly defined nomenclature. Compilations of available
data for sorption of metal cations and anions on gibbsite are
presented, and the results of surface complexation model fitting of
these data are given. The consistency of the thermodynamic surface
complexation constants extracted from the data is examined through
development of linear free energy relationships which are also used
to predict thermodynamic constants for ions for which insufficient
data are available to extract constants. The book concludes with a
comparison of constants extracted from data for sorption on
gibbsite with those determined previously for hydrous ferric oxide
(HFO), hydrous manganese oxide (HMO), and goethite.
The overall objective of this book is the development and
presentation of an internally consistent thermodynamic database for
sorption of inorganic cations and anions on gibbsite, an abundant
and reactive mineral in soils, sediments, and aquatic systems. Its
surface has a high affinity for sorption of metal cations and
anions, including radionuclides. The gibbsite database will enable
simulation and prediction of the influence of sorption on the fate
of these chemical species in natural systems and treatment
processes in which aluminum oxides are abundant. It thus will help
to advance the practical application of surface complexation
modeling.
