Abstract
The results of the study on changes in the structure and surface properties of montmorillonite from
Tagansky deposit from exposure to nitric acid of varying duration at an elevated temperature are presented in
this work. Treatment with 1M HNO3 solution causes partial leaching of octahedral and interlayer cations
which leads to protonation of internal surfaces and to an increase in microporosity as a result of octahedral
OH-groups protonation and change of octahedral Al coordination. The result of the exposure to acid solutions
is a change of layer charge and interaction between the sheets and layers with each other which in turn leads
to a significant increase of the specific surface area. Also, a reduction in the cation exchange capacity occurs
due to the deposition of amorphous silica from disintegrated tetrahedral sheets on the particle surfaces as well
as a reduction of the layer charge.
