- ... A mathematical model for reactive-transport processes in porous media is presented. The modeled system includes diffusion, electromigration and electroosmosis as the most relevant transport mechanisms and water electrolysis at the electrodes, aqueous species complexation, precipitation and dissolution as the chemical reactions taken place during the treatment time. The model is based on the local ...

- ... A physiscochemical model is presented for the reactive-transport of chemical scpecies through a contaminated soil during an acid-enhanced electrokinetic remediation treatment. Numerical simulations in the specific case of the removal of cadmium and lead from spiked kaolinite, compared with experimental results from the literature. The reactive-transport based on the local chemical equilibrium assu ...

- ... A generalized model applicable to soils contaminated with multiple species under enhanced boundary conditions during treatment by electric fields is presented. The partial differential equations describing species transport are developed by applying the law of mass conservation to their fluxes. Transport, due to migration, advection and diffusion, of each aqueous component and complex species are ...
