Nikolai Fedorovich Ermolenko (29.01.1900, v. Klyukovka, Orsha district, Vitebsk region – 10.06.1972) – chemist. Academician (1947; Corresponding Member since 1936), Doctor of Chemical Sciences (1935), Professor (1931). Honored Scientist of the BSSR (1949).

Work on the study of the laws of adsorption, synthesis, and directed changes in the structure, physicochemical properties of sorbents and catalysts. Established the phenomenon of sedimentation thixotropy for the case of adsorption of organic acids from their mixture in solution, gave a quantitative expression, reflecting the role of the "passivated" surface of the adsorbent. He developed a refractometric method for detecting compounds of higher order in solutions of salt mixtures and, based on the principle of physicochemical analysis, determined a number of such compounds. As a result of the study of the problem of the technical use of vegetable proteins (lupine), he developed a method for obtaining new types of plywood adhesives. He established the coagulation phenomenon in surface films, which he called laminar coagulation, on the basis of which the method of foam chromatography was developed. He proposed a theory of periodic sedimentation when the solvent evaporates dilute solutions of solids.

Author of more than 370 scientific papers, including 3 monographs.
