Abstract

The object of the research is spent bentonite, previously used for wastewater treatment to remove chromium (III) ions. Promising methods for the utilization of spent bentonites containing heavy metal ions within polyfunctional materials for polymer filling are identified. This approach will contribute to significant resource saving and environmental friendliness of industrial production. The structural features of carbonate-containing natural and spent bentonite clays were investigated and analyzed, and their main characteristics were determined using X-ray phase analysis and thermogravimetric analysis.
