Popis: The CO2 adsorption phenomenon in IRMOF-1 is considered on the basis of the cluster adsorption model. It has been shown that sorbate molecules are sorbed on the sorbent surface in the form of monomers and clusters of various dimensions. An explanation is proposed for the stepwise increase in the sorbate loading by the rapid sorbate adsorption as the n CO2 clusters within a narrow pressure range. For the studied system, equations are obtained that describe the experimental isotherms for temperatures 195, 208, 218, and 298K.
