Quadrupole mass spectrometer was used in the transient response technique as an analytical tool. With this technique the adsorptive characteristics of H_2 and CO on the modified Rh/Al_2O_3 catalysts were studied. It is found that a small amount of H_2 or CO was adsorbed irreversibly on the fresh surface of catalysts at 507 K; H_2 and CO are adsorbed on the same surface sites and CO adsorption is somewhat stronger than H_2 adsorption Addition of the potassium salt reduces the amount of adsorption of H_2 or CO, but enhances the difference of adsorption strength between CO and H_2.
