(2023) Danchenko, Yuliya; Andronov, Vladimir; Olijnyk, Halina; Kosse, Anatoliy; Rastorgueva, Mariia
The article presents potentiometric (pH-metric) methods that are used to study the acidbase properties of the surface of dispersed materials of different chemical nature. It is shown that the surface of any solid body has a surface hydroxyl-hydrate layer with a set of active adsorption centers (ACA) of different chemical structure and a wide range of acid-base properties. It has been proven that potentiometric (pH-metric) methods of studying dispersed materials in suspensions allow obtaining the most complete information about surface acid-base properties.
