Special Issue of Electrochimica Acta

A selection of papers from the 10th International Symposium on Electrokinetic Remediation will be published in a Special Issue of Electrochimica Acta edited by J.P. Gustav Loch.
Submissions for the Special Issue will be on invitation only. Deadline for submission of invited contributions: 15 October 2011. The procedure for the selection of papers will be devised and implemented by the Guest Editor in due course.

Welcome

Following the 9th EREM Symposium held in Taiwan at the National Sun Yat Sen University in June 2010, the 10th EREM Symposium in 2011 will take place at Utrecht University in The Netherlands. Apart from Utrecht University, the Technical University Delft, the Technical University Eindhoven and TNO – Built Environment and Geosciences in Delft are involved in organizing this symposium.

EREM Symposiums started in Europe in 1997, taking place every 2 years at different Universities and Research Centers: École des Mines d'Albi, (Albi, France, 1997); Technical University of Denmark (Lyngby, Denmark, 1999); Karlsruhe University (Karlsruhe, Germany, 2001); Belgian Nuclear Research Centre (Mol, Belgium, 2003); University of Ferrara (Ferrara, Italy, 2005); University of Vigo (Vigo, Spain, 2007); the New University of Lisbon (Lisbon, Portugal, 2009).

Due to the growing world wide interest, EREM started to be held outside of Europe in even years, and was organized by Korea Advanced Institute of Science and Technology in Seoul, Korea, in 2008.

Symposium Programme themes in 2011

1. Fundamentals of electrokinetic transport and related material properties.

Transport of ions, polar and non-polar molecules, micro-organisms and water in porous media like soils and porous building materials can be driven effectively by electrical potential gradients. These electrokinetic processes include electro-osmosis, electrolysis and electro-migration. Induced electrical phenomena, like streaming potentials and membrane potentials require flow to be described by a set of driving forces, e.g. gradients of hydraulic, chemical, electric and thermal potentials. Thus conductivity phenomena involving water, current and solutes under various driving forces are described by coupled phenomenological flow equations as described by the Onsager relationships. Prediction and measurement of the relevant coefficients are challenges for improving fundamental knowledge of electrokinetics.

Depending on specific surface area, surface properties of the pore wall in porous media may play a large role in electrokinetic transport. In clay mineralogy it is well established that electrostatic phenomena at the solid-liquid interface, e.g. double layer properties and structure (Stern layer, cation exchange capacity), organic matter properties and interaction between charged surfaces (DLVO theory and overlapping double layers), are the main origin of electrokinetic transport, i.e. electro-osmosis. Double layer polarization under the influence of electric, gravitational and pressure potential gradients is important in the coupling of transport processes. In addition solid/liquid interactions like solubilization, surface complexation and redox processes play important roles as well.

 

2. Application of electrokinetics in construction materials (incl. dehydration, stabilization, decontamination)

Electrokinetics, inclusive electromigration, is a powerful tool for removal and supply of matter into or out from porous building materials. Electrokinetic transport processes are therefore used in civil engineering for repair and maintenance purposes, e.g., chloride removal or realkalisation for corrosion protection, Li treatment of deleterious alkali-silica reaction or upgrading of fly ashes for use in concrete. These processes can also be used in conservation of porous materials as in desalination/dehumidification of brick masonry.

 

3. Applications of electrokinetics in inorganic soil decontamination.
4. Applications of electrokinetics in organic soil decontamination.

Electrokinetics has been applied for mobilization and cleanup of contaminants in soils and groundwater. In coarse grained materials ionic contaminants like metal ions migrate in the pore water when an electric field is applied. In clayey soils an electric field induces electro-osmosis, where contaminants may be mobilized by convection with the flowing pore water. For removal of non-polar organic contaminants from clays, electro-osmosis may be a key mechanism. Combination of this mechanism with surfactants and/or biodegradation may be a promising approach in future research and application.

 

5 linking fundamentals and applications (e.g. through models)

Characterization of the solid fabric structure, e.g. pore size, tortuosity, fractal dimensions, cohesiveness. Upscaling from micro to macroscopic behaviour with the use of mesoscopic experiments (i.e. at intermediate scale in the laboratory and in the field). Testing mathematical models on data from upscaled experiments. Verification of Onsager’s relationships for coupled transport.

 

6. Application of electrokinetics in non-soil/non-construction materials.
