  • Clays and Clay Minerals, Vol. 56, No. 2, 155–174, 2008. 
    S´rodon´, Jan; Mccarty, Douglas K. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    The total specific surface area (TSSA) and smectitic layer charge (Qs) calculated from the structural formulae and unit-cell dimensions of 12 pure smectite samples were used as a reference in the design and evaluation of ...
  • Clays and Clay Minerals, Vol. 57, No. 1, 115–133, 2009. 
    Wolters, Felicitas; Lagaly, Gerhard; Kahr, Guenter; Nueesch, Rolf; Emmerich, Katja (The Clay Minerals Society, 2009)
    The term ‘montmorillonite’ encompasses a wide range of chemical compositions and structures. Comprehensive and reliable characterization is essential for unambiguous classification. Twenty eight purified, Na-exchanged ...
  • Clays and Clay Minerals, Vol. 57, No. 3, 338–352, 2009. 
    Dohrmann, R.; Kaufhold, S. (The Clay Minerals Society, 2009)
    The cation exchange capacity (CEC) is one of the most important properties of clays in terms of their performance in both natural and technical processes. For decades, common methods for determining exchangeable cations ...
  • Clays and Clay Minerals, Vol. 57, No. 5, 649–671, 2009. 
    Srodon, Jan; Zeelmaekers, Edwin; Derkowski, Arkadiusz (The Clay Minerals Society, 2009)
    The nature of component layers of mixed-layer illite-smectite and their possible evolution in the course of illitization have been debated since the 1960s. The present study is a new attempt to solve these problems, using ...
  • Clays and Clay Minerals, Vol. 58, No. 1, 79–88, 2010. 
    Dohrmann, Reiner; Kaufhold, Stephan (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    The aim of the present study was to find methodological tools to obtain reasonable results for exchangable Ca2+ of gypsiferous bentonites. Cation exchange capacity (CEC) is an important property of clays. Numerous methods ...
  • Clays and Clay Minerals, Vol. 59, No. 6, 608–616, 2011. 
    Eggleton, Richard A.; Gerald, John Fitz (The Clay Minerals Society, 2011)
    Illite from Muloorina, just south of Lake Eyre in South Australia, is commonly used as a standard ferric iron-bearing illite which has a cation exchange capacity (CEC) of ~22 meq/100 g, too high a value for this clay to ...
  • Clays and Clay Minerals, Vol. 60, No. 1, 63–75, 2012. 
    Srodon, Jan; Kawiak, Tadeusz (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    This study uses the data from Miocene rocks of the Carpathian Foredeep to test the performance of the computer programs QUANTA and BESTMIN in aiding the interpretation of geophysical log data. These programs were designed ...
  • Clays and Clay Minerals, Vol. 60, No. 2, 162–175, 2012. 
    Dohrmann, Reiner; Genske, Dieter; Karnland, Ola; Kaufhold, Stephan; Kiviranta, Leena; Olsson, Siv; Plotze, Michael; Sanden, Torbjorn; Sellin, Patrik; Svensson, Daniel; Valter, Martin (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Bentonites are candidate materials for encapsulation of radioactive waste. The cation exchange capacity (CEC) has proved to be one of the most sensitive parameters for detecting changes of mineral properties such as swelling ...
