  • Physicochemical variation in bentonite by sulfuric acid

    [7] Activation of bentonite by acid is an important step for adsorption of some impurities by active clay This is socalled “activation process” The activation of bentonite is carried out in a continuous stirred tank reactor at low temperatures between 70 and 120oC in the presence of activation agents, mostly sulfuric acid During theThe activation of the Saudi natural bentonite with sulfuric acid was studied experimentally and the activity of the produced clay for bleaching of corn oil was tested and compared with that of commercial active clay The conditions that give best results for the sulfuric acid activation were found to be: 45% by wt acid concentration, liquid toStudy on the Activation of Saudi Natural Bentonite, Part I4 ) activation of the bentonite was conducted in a threenecked 05 liter glass flask Acid co ncentrations wer e prepared as 05, 1, 15, 2, 3, and 4 M A reflux condenser was attached to(PDF) Sulphuric Acid Activation of a Calcium Bentonite
