The work is devoted to a method that makes it possible to level the influence of sedimentation on the surface tension of slurry. To do so the methods for measuring surface tension are used, where the sedimentation process is multidirectional relative to the surface under study. An analysis of the results shows that the proposed method can virtually eliminate the influence of sedimentation on the surface tension of dispersed systems with low kinetic stability. Using the proposed method, the concentration dependence of the surface tension of aqueous slurries of bentonite in the range of 0–20 mass% of the solid phase is studied.
