Synthesis and Study of Physicochemical Properties of Mesoporous Carbon Sorbent Modified with 3-Phenylpropane Acid
Abstract—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.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
