Deposition velocities, V-d, reaction probabilities, gamma, and local adsorption parameters, k(1), describing the isotherms of ethane, ethene, ethyne, propene and 1-butene onto three solid pigments (PbO, Fe2O3, CdS) have been determined in the absence and in the presence of NO2, together with the surface reaction rare constant, k(2), and the desorption rate constant, k(-1). The calculations are based on experimental adsorption isotherms, since the linear adsorption model is not a very good approximation for inorganic solids like those mentioned above. The important result found is the effect of NO, on the values of the parameters V-d, gamma, k(1), k(-1) and k(2) in most cases. (C) 1997 Elsevier Science B.V. (EN)
