Activation of bentonite by acid is an important step for adsorption of some impurities by active clay [6]. This is so-called "activation process". The activation of bentonite is carried out in a continuous stirred tank reactor at low temperatures between 70 and 120 °C in the presence of activation agents, mostly sulfuric acid [7].

Activation of Bentonite clay using hydrochloric acid (HCl) [15], [16], sulfuric acid (H 2 SO 4) [17], [18] and other acids [19], [20] has been reported. Out of all acids, H 2 SO 4 is preferred mostly as the activation can be performed by mild process conditions and the quality of the end product is better with high specific surface area and ...

Bentonite production process features ore mining, sodium activation – if required -, drying, and milling. Sodium activation is performed to convert calcium bentonite to sodium bentonite, in which calcium ions are exchanged for sodium carbonate. Through drying, bentonite natural moisture content of about 25-35% is reduced.

The activated bentonite-based bismuth ferrites (A-BiFe/Bent) by mechanical activation was obtained. The catalytic activity of A-BiFe/Bent was improved about by 1-fold than that of unactivated composite. The influence of activation parameters on the photocatalytic activity and the physicochemical change of A-BiFe/Bent were investigated.
