introduction on bentonite

Bentonite - an overview ScienceDirect Topics

Introduction. Compacted bentonite is a major packing and storage material, due to its extremely low hydraulic conductivity. Although the physical transport through bentonite is limited, it is also essential to understand the mechanisms of radionuclide sorption on important reactive mineral surfaces present in
