Potential gradient, development during

During the transition time, a variety of processes of adjustment take place development or change of an ohmic potential gradient, a change in EDL charge density, the development of concentration gradients in the electrolyte, and so on. Each of these processes has its own rate and its own characteristic time of adjustment. 

Alshawabkeh and Acar [134] developed a theoretical model describing contaminant transport during electrokinetic remediation, based on the equilibrium chemistry of the solution and the electrochemical properties of the contaminants within the soil. The model demonstrates that the removal of ions from soils is caused by a combined effect of electrical, hydraulic, and concentration potential gradients that exist in the soil. The factors controlling the rate of change of these potential gradients included the volume compressibility and electrical capacitance of the soil, and the conductivities of the ions. 

Application to capacitively-coupled reactors Figure 24a shows the electron temperature distribution in an argon discharge sustained in a one-dimensional parallel plate reactor of the kind shown in Fig. 7. The temperature peaks near the plasma-sheath interface, where the product of the current and electric field (Eq. 31) is highest, and steep gradients develop in that region. Electrons which diffuse towards the electrode during the sheath potential minimum (around r = 0.25 at left electrode, see also Fig.
