Properties of Electrochemically Produced Nano-Sized Unimodal Bentonite-E

Resumo

A nano-sized unimodal montmorillonite fraction (bentonite-E) with low metal-carbonate contents was isolated from native clay from the Gerpegezh deposit (Kabardino-Balkaria Republic) using an electrochemical method with lead and copper anodes. The elemental composition, chemical structure and morphology, and thermal properties of the obtained samples were studied using contemporary physicochemical methods (volumetry, IR spectroscopy, x-ray powder diffraction, laser-diffraction particle-size analysis, x-ray crystal structure analysis, thermal analysis).
