Abstract: The desorption of oligomers/copolymer of glycolic and lactic acids from the surface of the synthesized modified sorbents in a 0.9% NaCl saline solution was studied by means of 1H NMR spectroscopy, pH-metering and low-temperature nitrogen adsorption. It was found that contact of the modified sorbents with a saline solution leads to a gradual desorption of the modifiers with biospecific properties as mono-, di- and trimers from the sorbent surface via hydrolysis. The desorption of deposited modifiers was shown to increase specific surface area of the material and decrease pH of the medium. A low (< 4) pH of the biological medium, which is obtained upon contacting with the modified sorbent, will promote the death of pathogens and infectious agents. The synthesized carbon materials can be recommended for use in sorption therapy.
