“…The results obtained show that SSA is adsorbed better and more completely than salicylic acid [12]. Presumably, the key role is played by the solubility of these phenolic acids in water, which is higher for SSA as compared to salicylic acid due to the presence of a sulfogroup.…”

The adsorption properties of a carbon sorbent with respect to sulfosalicylic acid from individual solutions and upon addition of amino acid (arginine, phenylalanine) were studied. The addition of amino acids to an aqueous solution of sulfosalicylic acid was shown to increase the amount of adsorbed sulfosalicylic acid on the carbon sorbent. Carbon sorbents before and after the adsorption/desorption of biologically active substances were studied using various physicochemical methods (low-temperature nitrogen adsorption, spectrophotometric method, thermal analysis, et al); adsorption properties of the tested samples toward the substances modeling toxic compounds (methylene blue, metanil yellow) were estimated. The modified samples in the presence of amino acids showed high adsorption capacity toward methylene blue dye. The produced materials are recommended as enterosorbents for treatment of gastrointestinal disturbances.
