Electrosurface characteristics of porous glass particles [Elektronische Daten] [L. Ermakova, A. Volkova, T. Antropova, A. Zhukov] The surface charge and electrophoretic mobility of particles of porous glasses with different compositions have been studied in potassium nitrate solutions with concentrations of 10−3-10−2 M. It has been shown that the surface charge in KNO3 solutions virtually coincides with the charge in KCl solutions and has negative values in the studied pH range of 4-9. The concentrations and mobilities of ions in glass pores, Donnan potentials, and the convection component of electrical conductivity have been calculated within the framework of a homogeneous model. Electrokinetic potentials of the glasses under investigation have been calculated with regard to the effect of the electrolytic conductivity of the porous particles and electroosmotic transport in the pore space on the electrophoretic mobility.
