SPECIAL SECTION: RECENT DEVELOPMENTS IN SURFACE COMPLEXATION MODELING

摘要

This special section on surface complexation modeling contains papers presented during the special session "Recent developments in surface complexation modelling: Trace element speciation and reactive transport modelling" at the 12th International Conference on the Biogeochemistry of Trace Elements (ICOBTE), which took place 16-20 June 2013 in Athens, Georgia, USA. Ion-binding and surface complexation models have been developed during the past 2 decades to describe equilibrium trace element binding to complex reactive components of the surface and near-surface environments, including natural organic matter, hydrous metal oxides, and clay minerals. Because of their semi-mechanistic and process-based nature, these models are applicable over a wide range of conditions and have potentially powerful uses in hazard and risk assessment of metals and metalloids.
