Comparative analysis of the adsorption properties of a carbon sorbent modified with sulfosalicylic acid solutions in the presence and absence of amino acids

The adsorption properties of a carbon sorbent in relation to sulfosalicylic acid in an individual solution and with an added amino acid (arginine or phenylalanine) were determined. It has been shown that the addition of arginine to an aqueous solution of sulfosalicylic acid leads to an increase in the amount of sulfosalicylic acid adsorbed on the carbon sorbent. The sorbents modified in the presence of amino acids showed high adsorption capacity for the methylene blue dye.
