Development of Thermodynamic Sorption Databases

In contrast to thermodynamic databases for modeling aquatic species or solid phase solubility, the development of databases with surface complexation data (SCM) for modeling sorption is not well advanced. This is due to the nature of sorption modeling, which ranges over a multitude of competing models and a wide variation of surface complexities. In addition to the RES³T SCM database or the JAEA Kd database, the data are mainly available as individual publications or books with a small amount of data. The talk addresses the logical requirements of a reference database for sorption data and quality assurance with respect to the assumed surface species.
