METHOD AND DEVICE FOR DETERMINING A FLOW POTENTIAL OR ZETA POTENTIAL

摘要

The present invention relates to the method and apparatus for determining a force and velocity of a current or zeta potential, in order to characterize the surface charge behavior of macroscopic solid body. For keeping the macroscopic body other than electrolyte solution and liquid, bipolar electrode (2,3) is provided by measurement battery (1) is limited by pressurization. According to the present invention, liquid is limited by oscillation or regularly variable pressurization and each pressurization, and the force and velocity of a current is determining or records. Simple structure allows the quick measurement of the force and velocity of a current or zeta potential.
