Abstract
Results obtained in studies of coagulation behaviour of some
hydrophilic (rutile) and hydrophobic (graphitised carbon black
Sterling MTG) materials in solutions of the anionic surface active
agent Aerosol OT (Na-di-2-ethylhexyl sulphosuccinate) in hydrocarbons
(xylene) are discussed. Using particle sizes, determined
by electron microscopy, and zeta-potentials, obtained from microelectrophoretic measurements, as parameters to calculate energy
barriers, it was found that the Deryaguin-Landau-Verwey-Overbeek
theory allows satisfactory quantitative interpretation.
