ZETAPOTENTIAL DETERMINATION FROM ELECTROP HORETIC MOBILITY MEASUREMENTS

Electrophoretic techniques are the main methods for the experimental i nvestigation of the zetapotential of dispersions and emulsions. The ob jective of the paper is to describe some aspects of the theoretical fo undations. The calculation of the electrophoretic mobility and the zet apotential based on velocity measurements of particles in an electric field is discussed In the second part the interest is addressed to som e methodical aspects of the mainly used experimental microelectrophore tic techniques.
