ELECTROKINETIC REMEDIATION. II: THEORETICAL MODEL
The authors present a mathematical model for multicomponent species transport under coupled hydraulic, electric, and chemical potential variances. Mass balance of species and pore fluid combined with charge balance across the medium result in a set of differential equations. Sorption, aqueous phase, and precipitation reactions are represented by a set of algebraic equations. Instantaneous chemical equilibrium conditions are assumed. Transport of four chemicals, the associated reactions, electric potential, and pore pressure distribution across the electrodes in electrokinetic remediation are simulated. Model predictions of acid transport, lead transport, and pore pressure distribution exhibit very good agreement with the pilot-scale test results, confirming the formalisms offered for multicomponent transport of reactive species under an electric field. The model also bridges the gap between the electrochemistry and mechanics in electroosmotic consolidation of soils.
