Summary:Title screen
The work focuses on the solution of the problem concerning the diagnostics and prognosis of water-absorbing capacity of polydisperse materials. The relation of water absorption and acid-base properties of the surface is considered. The advantages of the research of acid-base properties of the surface by the pH-metry method are illustrated. The algorithm of the processing and interpretation of pH metric results to diagnose water absorption of powdery substances is suggested. The diagnostics is based on the research of velocity variation of mass transfer in the reaction zone in time. The change of pH suspension per unit of time is considered for the first time as an analytic signal of "WрН" mass transfer velocity. It is demonstrated that the velocity variation of mass transfer in the system "solid body-water" reflects the stopping mechanism of ion exchange and can be used for prognosis of hydrophobic behavior of the solid body surface. The introduced material in the given article will be useful for implementation in research, industrial and school laboratories.
