SOPRO 2004. International workshop on sorption processes at oxide and carbonate mineral water interfaces

SOPRO 2004 is the fourth meeting in the series ''Karssruher Geochemical Workshops''. The first workshop, held in 1997 at the Forschungszentrum Karlsruhe, was entitled ''Geochemical modelling - radio toxic and chemical toxic substances in natural aquatic systems''. The second meeting was held in 1999 in Speyer focusing on ''Mineral/water interactions close to equilibrium''. The third workshop, held in 2002 in Karlsruhe, dealt with ''Modelling of coupled transport reaction processes''. SOPRO 2004 is intended to deal with sorption processes. These are for example relevant for retention of radionuclides migrating from nuclear waste repositories. General focus will be on fundamental studies from an experimental and theoretical point of view. The intention of SOPRO 2004 is to serve as a possibility to discuss the state of the art and our understanding of sorption processes at mineral water interfaces. Focus will be on oxide and carbonate minerals. The workshop intends to cover a broad range of experimental techniques (classical chemistry studies, surface spectroscopy), modeling aspects (such as surface complexation modeling), theoretical approaches (quantum chemistry) and the synthesis of results in data bases. The present report includes extended abstracts of the contributions presented at SOPRO 2004. (orig.)
