The Authors dealt with the use of modified clay materials for the removal of dangerous industrial pollutants. Three modification methods (namely modification by Kegginďż˝s polycation, modification by means of humic substances and pillarization at 450 ďż˝C) were applied for the creation of modified materials. Clay materials modified by humic substances were used for the sorption of Cr(VI) from aqueous medium in the form of dichromates. Other ways of modification and their combinations were used for the preparation of the sorbents of dangerous gaseous pollutants (toluene, xylene). It was discovered that some modified clay materials sorb the gaseous pollutants twice as much as common sorbent (activated carbon).
