Zeta potential measured for an intact granite sample at temperatures to 200°C -: art. no. 1295

[1] Streaming potential was measured in an intact granite sample, saturated with aqueous KCl solutions at three different concentrations, at temperatures between 25degrees and 200degreesC. The magnitudes of the streaming potential coefficient and of the surface conductance (which dominates the sample conductivity) both increase with increasing temperature. Using a capillary model, we found that the magnitude of the zeta potential also increases with increasing temperature.
