Vergleichende Messungen des Zeta-Potentials von Faserstoffen durch Elektroosmose und Strömungsstrom/Strömungspotential

摘要: An apparatus for the determination of zetapotential is described, which allows measurement both streaming potential and current as well electroosmosis with one same fiber diaphragm various electrodes (calomel, Ag/AgCl, palladium). Measurements glass fibers, fibers polyacrylonitrile polyester, cellulose pulp show that identical values electrokinetic parameters are obtained independent voltage applied during resp. pressure difference measurements. This conclusion in dilute electrolyte solution here an unequivocally determinable figure.
