MEASUREMENT AND APPLICATION OF ZETA-POTENTIAL

Abstract

The electrokinetic or zeta-potential is an important parameter of the electrical double layer and represents a characteristic of electrical properties of solid/liquid and liquid/gaseous interfaces. In the paper electrokinetic phenomena in this contact are described as well as measuring methods. Changes of the values of zeta-poten-tial depending on some properties of solid/liquid interface are being considered.
