    Modification of sodium montmorillonite with zirconium polycations was carried out. As a result, a microporous, non-swelling, thermally stable structure was obtained. Such material can be used in environmental protection as a catalyst support in the removal of toxic volatile chlorinated organic compounds. The possibility of using Zr-PILC as a kind of storage for carbon dioxide was also examined. Thermal analysis combined with the analysis of the emitted gaseous products showed that this material absorbs certain amount of carbon dioxide. CO2 removal begins at temperatures above 250° C and continues until 800° C. Carbon dioxide binding involved both the outer and the inner surface of Zr-PILC, occurring in different locations, with different intensities. Zr-PILC dried at 200° C for 4 hours binds CO2 more strongly than the not dried Zr-PILC..
