To determine the structure and composition of bentonite samples, X-ray phase, electron microscopic, thermal and spectral analyses were carried out. X-ray diffractogram XRD Empyrean PANanalytical X-ray diffractometer allows for automation of the research process, and data recording and processing using a personal computer using the PDWin and PELDos software packages. The presence of a dioctahedral montmorillonite reflex d020 = 0.446 nm confirms the presence of two octahedral aluminum or magnesium layers separated by a tetrahedral silicon layer in its layered arrangement. The main sorption activity of the montmorillonite mineral is 54-56 wt% in the B1 clay sample, and about 54-57 wt% in the B2 sample.
