complete the activation process (Harvey and Lagaly, 2006). Following activation and drying/curing period for a month, the activated samples were crushed to its original size of N150 µm using mortar and pestle. Swelling tests were performed in 100 ml graduated cylinders using 2 g bentonite dried at 105 °C using halogen driers. After slowly

bentonite and acid activated bentonite. Calcium-Bentonite or non-activated bentonite is type that is predominantly occupied by Ca2+ or Mg2+-ions in the intermediate layers. Activated Bentonite has initial composition of Ca2+-ions in the intermediate layer replaced with Na+-ions in a technical process known as alkali-activation.

Acid Treatment of Bentonite: Under the influence of a mineral acid the exchangeable alkaline earth ions of bentonite are substituted by hydrogen ions. Moreover, depending on the acid concentration, temperature, pressure and reaction time, a more or less pronounced leaching process takes place. Thereby Al-, Fe- and Mg-ions are extracted from the octahedron layers.

Aug 26, 2019 · Activated clay is clay, usually of bentonite origin, which has been treated to improve its ability to adsorb. The clay is processed with acid, upping the adsorption properties of the clay considerably. Once it has been treated, activated clay can also be reactivated as it is used, allowing people to reuse the clay rather than having to continually replace it.
