Determine the zeta potential at the ceramic filter/potassium chloride aqueous solution interface if the flow potential is 6.5 mV when the solution is flowing at a pressure of 20kPa. The specific electrical conductivity of the medium is 0.013 Sm•m¯¹, the viscosity is 1.00 mPa•s, the relative permittivity of the solution is 80.1, and the surface conductivity of the ceramics is neglected.
