Flow Caused by Applied Electric Field Exogen Transport

1 Flow Caused by Applied Electric Field (Exogen Transport) 

Free amino acids, proteins, ions, colloidal particles, bacteria, and cells are possible charged particles migrating in an electric field therefore, they can be studied by electrophoresis. As described in Section 7.5, some molecules of the solvent are attached charges on the particle hence, some solvent will move together with the particle. This is a part of the electrophoretic effect. 

Electrophoretic flux could be calculated from the zeta potential, the permittivity, and the viscosity. Because these quantities are difficult to estimate, electrophoretic mobility is a more practical quantity. Migration velocity is simple to measure, and the different electrophoretic mobility is the basis of a very powerful in vitro analytical tool for amino acids and proteins in clinical laboratories (Table 2.8). 

Electro-osmosis is the transport of bulk liquid through a pore under the influence of an electric field. The volume of solution transported per unit time, V, is 

Electro-osmosis is a kinetic process that is used for the determination of the zeta-potential of a surface/electrolyte solution interphase. It is also a process found in the sweat pores of
