The natural bentonite was purified in the laboratory to remove calcite, carbonates, and organic matters by the following protocol: the sample was first repeatedly washed with Milli-Q water and dried after each time. The dried bentonite clay (25 g) was soaked in 400 mL solution containing Na-Ac (0.1 N) and Ac-Ac adjusted to pH ≈ 5.0.

Fisher and Schmincke (1984) suggest that the nomenclature of bentonites should reflect the dominant clay mineral species with smectite (s)-bentonite, kaolinite (k)-bentonite and illite (i)-bentonite. K-bentonite is a well-established term and Huff (1983) has made a good case for its retention. Likewise the term tonstein is also well …
