Determination of pore water composition during long term interaction of bentonite substrates with water media: Comparative study

Popis výsledku v původním jazyce

Knowledge of pore water composition is crucial information in research of long-term stability of bentonite and is also crucial for any stability predictions based on geochemical modeling. This paper reports validation results of two frequently used extraction methods centrifugation and leaching. Three types of bentonite materials were used in our study. The first one was the Czech raw bentonite from the Rokle deposit. The second type of bentonite was "Mock-Up-Cz", which is a mixture of bentonite material from the Rokle deposit with finely ground quartz and graphite powder. The third type of material was the FEBEX bentonite obtained from the Cortijo de Archidona deposit. All the bentonite samples were placed into pressure vessels and interacted with natural water during a one-year experiment. Free water, obtained during these interactions, was used as a comparative pore water composition for both of the extraction methods. The high water content in saturated bentonite, reaching about 50
