Modification of carbon sorbent by sequential adsorption of biologically active phenylalanine and salicylic acid

The sequential adsorption of phenylalanine and salicylic acid on a carbon sorbent was studied. The influence of modification conditions, including the sorbent/solution volume ratio, amino acid concentration, temperature and pH, on the adsorption parameters of phenylalanine, as well as the physicochemical properties of the resulting carbon sorbent sample, was established. The effect of sequential adsorption of phenylalanine and salicylic acid on the physicochemical characteristics of sorbents is shown.
