Streaming-Potential Effects in Saturated Water Flow through a Sand-Kaolinite Mixture
That the viscous flow of water through a capillary tube or a watersaturated porous medium can give rise to an electrical streaming potential, directed oppositely to the direction of liquid flow, is a well-recognized phenomenon normally accounted for in terms of the electrical double layer (Abramson, 1934; Overbeek, 1952). Several recent reviews with special emphasis on soil water are available (Ravina and Zaslavsky, 1968 a, b). To investigate the role of zeta potential in the mechanism of sand filtration, Edwards and Monke (1967a, b) have sought to use streaming potential, while Abaza and Clyde (1969) have suggested it as a measure of water flow rate.
