About changes in composition and mineralization of pore waters during their squeezing from clays
Abstract
In recent years, more and more attention of researchers is attracted to the study of sedimentation waters of clayey rocks.It has been noted that as the solutions are squeezed by the application of individual load steps, mineralization in subsequent portions of the solution continuously decreases. This regularity was tried to explain by the action of filtration effect, influence of membrane equilibrium, different dissolving capacity of different categories of bound water. Currently, an increasing number of researchers are inclined to the fact that the difference in mineralization of subsequent portions of the solution indicates the existence near the surface of the solid phase of some part of the solution with a reduced concentration of dissolved salts - the so-called bound solution.
