Adsorption of water vapour by natural and chemically modified clinoptilolite and mordenite samples
Water vapour adsorption-desorption properties of natural clinoptilolite (N–CLI) and mordenite (N-MOR) samples (Trans-Carpathian region, Ukraine), their acid modified forms, Н–CLI–6 and Н-MOR-6, and catalysts for both CO oxidation, Pd(II)-Cu(II)/Н-CLI-6 and Pd(II)-Cu(II)/Н-MOR-6, and ozone decomposition, MeCl <sub>2</sub>/N-CLI (Me = Cu, Co, Mn), have been studied. All adsorption isotherms at p/ps <0.4 are described by BET equation with correlation coefficient R <sup>2</sup> = 0.99. The activity of the catalysts depends on water content in samples.
