Comparative analysis was performed of local bentonites of SPECJAL EXTRA U and IZOL types, produced by Zakłady Górniczo‐Metalowe Zębiec, and of LT type bentonite, produced by Rheox company. Principal physicochemical properties of the bentonites were established, including bulk density, capacities to absorb water, dibutyl phthalate and paraffin oil and their sedimentation rates in water, xylene and gasoline were estimated. Bentonite morphology was examined using scanning electron microscope (SEM). Moreover, particle size distribution, BET surface area and zeta potential were determined.
