The adsorption isotherms of some dipeptides composed of un-ionizable side chains were measured at 25°C in a single component system, and all of them obeyed the Langmuir equation. The parameters obtained at pH 7 could be roughly correlated with the hydrophobic and steric parameters of constituent amino acids. To find a method for predicting the amount of dipeptide adsorbed under various conditions, the applicability of the Polanyi adsorption potential theory was examined. The amount of dipeptide adsorbed could be roughly estimated from the adsorption isotherms of the amino acids, although the estimation lacked strictness in a physical sense.
