Zusammenfassung:—The adsorption of 3-phenylpropanoic acid on a mesoporous carbon sorbent was studied. The optimal ratio and equilibrium time in the sorbent–phenylpropanoic acid solution system were determined. A method for modifying a carbon sorbent with 3-phenylpropanoic acid has been developed. The possibility of migration (desorption) of the modifier into solutions simulating the environment of the stomach and intestines was investigated. The set of physicochemical research methods—low-temperature nitrogen adsorption, IR, NMR, X-ray photoelectron and Raman spectroscopy, spectrophotometry, the titrimetric method of H.P. Boehm, CHNOS elemental analysis—were used to study the properties of a carbon sorbent before and after modification, as well as after desorption of the deposited 3-phenylpropanoic acid. The synthesized modified samples are promising for use as enterosorbents for treating gastrointestinal diseases.
