A condensation reaction of glutamic acid with glycine in bulk is conducted and studied. Condensation of amino acids on the surface of a mesoporous carbon sorbent is performed on the basis of the found conditions of bulk synthesis. The sorbent/solution ratio and synthesis duration are varied in the process of surface modification. The processes of desorption of the applied modifiers from the surface of the sorbent in aqueous solutions are modeled and studied. The properties of the samples of the sorbent before and after modification, as well as after desorption of the introduced modifiers, are studied and compared by physicochemical methods such as low-temperature adsorption of nitrogen, thermal analysis, acid–base titration by the Boehm method, and X-ray photoelectron spectroscopy. The regularities of the condensation reaction of amino acids on the carbon sorbent are found. The optimum conditions of preparation of modified carbon materials for the purposes of sorption medicine are determined. It is found that the sample obtained at a sorbent : solution of amino acids ratio of 1 : 5 at a duration of the thermal treatment of 1.5 h at 190°C is the most promising.
