Measured adsorption-desorption isotherms of nitrogen on selected aggregates. Identified micropore filling and mono-multilayer adsorption at aggregate surface. Performed adsorption tests of three known probe vapors on selected aggregates. Compared isotherm models in terms of physical significance & goodness of model fit. Proved DA model the best for modeling adsorption isotherms of vapors on aggregates.
