Bentonite Properties/ Specification - Arij Trading

Na Bentonite is mostly filled by Na2+ ions in the middle layers. Ca2+ or Mg2+ ions can also happen usually in Sodium bentonite in changeable concentrations. Activated Bentonite has the primary composition of Ca2+ ions in the middle layer exchanged with Na+ ions during a technical process known as alkali activation.

Activated bentonite was obtained from acid activation and purification of raw bentonite, sorption of Th(IV) onto activated bentonite was studied by batch experiments. Characterization of activated bentonite and sorption behavior of Th(IV) demonstrated that Th(IV) could quickly absorbed on activated bentonite, and kinetic process fitted well with the pseudo …


Bentonite - an overview | ScienceDirect Topics

Activated calcium bentonite is the most widely used bentonite in winemaking as it has a high swelling index and a pH of between 9 and 10. It also has a high proportion of exchangeable sodium and calcium. It is obtained by activating natural calcium bentonite with sodium carbonate, and then drying and grinding the resulting mixture.
