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.

3-苯丙烷酸改性介孔碳吸附剂的合成及理化性能研究

摘要研究了介孔碳吸附剂对3-苯丙酸的吸附性能。确定了吸附剂-苯丙酸溶液体系的最佳配比和平衡时间。研究了用3-苯丙酸对碳吸附剂进行改性的方法。研究了改性剂在模拟肠胃环境的溶液中迁移(解吸)的可能性。采用低温氮吸附、红外、核磁共振、x射线光电子和拉曼光谱、分光光度法、H.P. Boehm滴定法、CHNOS元素分析等理化研究方法，研究了沉积的3-苯丙酸改性前后和脱附后碳吸附剂的性能。合成的改性样品有望作为肠道吸收剂用于治疗胃肠道疾病。
