Abstract
The exchangeable ions in Tinpahari bentonite were substituted by Na+, K+, NH4+,
Mg+2, Ca+2, Ba+2, Al+3 and ThH ions separately. The amount of interlayer water
in bentonite is fairly large (about 10-15%) and the water content is determined primarily
by the principal exchangeable cation present. The dehydration-rehydration
flexibility of the bentonite as well as the cation exchange characteristics have been
studied and the specific role of the exchangeable cations has been examined.
