1 Cationic Heavy Metals Numerous studies are reported on the electrokinetic removal of heavy metals from soils (Chapter 4). Many of these studies used ideal soils, often kaolinite, as a representative low-permeability soil, which were spiked with a selected single cationic metal (such as lead and cadmium) in predetermined concentration. The spiked soil is loaded in a small-scale electrokinetic test setup and electric potential is applied. The transport and removal of the metal after specified test duration are determined.

Hence, the electroneutrality in an electrochemical system will hold when the charge density is small compared with the total ion concentration, Ceq, of the bulk fluid; that is, |C+ − C−| << C+ + C−. g. electric double layer for which Debye length is the width of the layer), electroneutrality can be achieved considering Nernstian boundaries and faradic reactions. , 1994; Eykholt and Daniel, 1994; Hicks and Tondorf 1994; Shapiro, Probstein, and Hicks, 1995; Alshawabkeh and Acar, 1996; Electorowicz and Boeva, 1996; Yeung, Hsu, and Menon, 1996; Dzenitis, 1997; Reddy and Parupudi, 1997).

When charged ions transport under the influence of an externally applied electrical field, their concentration distributions change with time, which lead to a change in local electrical conductivity. The change in local electric conductivity directly alters the value of potential gradient at that specific point. Hence, the changing electric conductivity and electrical field describe the transport process of the species implicitly. The migration of the ions in the bulk fluid are modeled taking into consideration the changing electric field due to migration, as well as other effects such as retardation and electropheretic effects that reduce ionic mobility.
