Year: 2025
Type: article
Abstract: The research subject was bentonite clay of layer II from the Dashukivka area of the Cherkasy deposit. The clay was enriched with montmorillonite using sedimentation, followed by the production of particles with a fraction size of ≤ 0.001 mm. Both natural montmorillonite and the nature of isomorphic substitutions in its structure were confirmed through X-ray diffraction and comprehensive thermal analyses. The activation of montmorillonite-rich bentonite clay was achieved through ultrasonic waves. The sorption capacity of natural bentonite and ultrasonically modified enriched bentonite against Cu²⁺ ions was assessed by modeling the sorption isotherm data, using the Langmuir equation. The Cu2+ ions sorption mechanism was studied using energy-dispersive and diffractometric X-ray analyses. The research provided an analysis of applications of natural bentonite and ultrasonically modified enriched bentonite clay.
