Description

Surface Complexation Modelling deals with various aspects associate to the modelling of solutes adsorption from of solutes from aqueous solutions to minerals. The individual contributions cover fundamental aspects and applications. Applications cover case studies and present consistent surface complexation parameter sets. The model approaches range from simplistic to mechanistic. More fundamental contributions address underlying phenomena or stress the opportunities of modern computational methods. Several mineral systems are covered, including goethite, gibbsite, clay minerals etc.
Surface Complexation Modelling presents the state-of-the-art of surface complexation modelling and suggests ideas for further model development. A number of chapters are authored by scientists working on nuclear waste storage, where the retention of radionuclides contributes to preventing radionuclide migration from the repository to the biosphere. Other contributions come from soil and environmental chemists with an interest in reactive transport of pollutants in soils or aquifers.

About the editor

Johannes Lutzenkirchen

Dr. Johannes Lützenkirchen has been involved in surface complexation modelling for nearly 25 years. Starting with his PhD studies in Strasbourg (France), influenced by co-workers of Werner Stumm (aquatic chemistry), continuing with a post-doc in Umea (Sweden) in an environment that combines influences of Lars Gunnar Sillen (solution speciation) and Paul Schindler (surface complexation), and subsequently gaining some insight in consulting at Colenco (Baden, Switzerland) related to nuclear waste disposal with focus on long term safety assessment, he has currently been employed at KIT for more than 15 years. At the Institute for Nuclear Waste Disposal (INE), he is mainly involved in surface studies and to some extent in reactive transport modeling. On web-of-science he presently has more than 90 publications. He has edited one book, and written several book chapters. His main research interests and activities continue to be directed at understanding solution and mineral surface reactions of dissolved radionuclides. He has also some interest in fundamental studies on water solid interfaces and water structure.
