Sažetak
Conditions for obtaining quantitative .ililformation on the double
layer of colloid particles on the basis of electrosurface measurements
have been analyzed. A rigorous theory of electric conductivdty
of diluted suspensions on the basis of induced dilpole
moments of particles has been presented.
The .isoconductance point of a suspension has been shown to
codncide wd.th the isopolarisation state of a particle. A theory of
anisotropy of the electrophoresis of long rod-like particles has been
put forward. The identity of the formules of electrophoresis of a
sphere and of cylindrical particles oriented pevpendicular towards
the field at a small thickness of the double layer has been shown.
A good agreement has been found between the values of induced
dipole moments and, specific surface conductivity in a wide electrolite
concentration range measured by the methods of electric
conductivity of suspensions and anisotropy of electrophoresis. The
theories of induced dipole moment, electric conductivity of suspension
and anisotropy of electrophoresis have been experimentally
examined.
