Rehydration Driven Acid Impregnation of Thermally Pretreated Ca-Bentonite—Evolution of the Clay Structure
A new approach to acid activation of raw Ca-bentonite was explored. The method consisted in dehydration of clay by thermal pretreatment at 200 °C, followed by immediate impregnation with H(2)SO(4) solution. The acid concentration was 1.5 × or 2.0 × cation exchange capacity (CEC) of clay. The volume...
