INTRODUCTION OF BENTONITE: Bentonite is a kind of clay, often containing a small amount of illite, kaolinite, chlorite, Elo stone, quartz, feldspar, zeolite and calcite, which hardness is 1 ~ 2 and density is of 2 ~ 3g/cm3. According to the kinds of exchangeable cation, content and layer charge, bentonite can be divided into Na…

The effect of initial ammonium concentration on the adsorption process onto natural bentonite was investigated at different initial ammonium concentrations, ranging from 10 to 10,000 mg-NH 4 + /L, with bentonite/solution ratio maintained as 0.1 g/25 mL. The suspension was stirred in 100-mL conical flasks using a rotatory incubator at a 120-RPM ...

Bentonite, when used as buffer/backfill material in the deep disposal of high-level radioactive waste (HLW), could undergo desiccation shrinkage or even cracking due to the heat released from HLW, impairing the efficiency of the barrier system. Furthermore, in-service buffer materials are inevitably in contact with the groundwater, which sometimes contain high salt concentrations.

For the high-value utilization of hemicellulose-based composite films, the poor film-forming and mechanical properties of hemicellulose-based composite films must be surmounted crucially. Based on this, hemicellulose-based organic-inorganic composite films with good mechanical properties were prepared from quaternized hemicelluloses (QH), bentonite, and polyethyleneimine (PEI).
