Stabilization of aqueous suspensions of palygorskite by thermal vapour pressure shock explosion (TSE) treatment
clay minerals palygorskite thermal vapour pressure shock explosion
2011/11/10
Abstract A device was constructed in which a clay suspension is hermetically heated at 220°C for a few minutes. This thermal treatment is accompanied by a pressure increase in the cell. Once the valv...
Sorption–desorption of cadmium in aqueous palygorskite, sepiolite,and calcite suspensions: Isotherm hysteresis
Cd Hysteretic adsorption Release Reversibility
