clay samples which were submitted to acid treatment with sulfuric acid at different concentrations and the XRD of natural montmorillonite clay and treated montmorillonite clay ( mol L1), respectively. For the materials studied, was observed the presence of bands at 3456 cm 1 related to internal and external hydroxyl
you can activate the clay by adding your clay in 8M HCl,H2SO4 for refulxuing for 12 to 14 hrs will give you strong H+ clay
In a process of acid activating a subbentonite clay in which the clay is treated with sulfuric acid, washed to remove soluble salts and residual acid and dried, the improvement which comprises compressing said clay into forms having increased density of at least 7% over the particles of said clay before such compressing, prior to the acid treatment.
extracting the alumina from the calcined clay by leaching with 3M sulfuric acid, and using an acid to clay ratio of 80 wt% at 100oC for 120 min. An aluminum dissolution efficiency of % was achieved under the conditions that resulted in the maximum dissolution efficiency of iron ( %).

Sulfuric acid is employed in petroleum technology in various ways, and the end product of its utilization is usually a sludge composed of unreacted sulfuric acid, petroleum sulfonates, including the sulfonic and sulfinic acids of the hydrocarbons present in the petroleum to be treated, and also sulfuric esters of complex character together with dissolved hydrocarbons usually of olefinic character.
Acid Treatments of Montmorilloniterich Clay for Fe Removal Using a Factorial Design Method Some previous studies5,12 using sulfuric acid and hydrochloric acid report reductions of approximately 75% to 40% in the Fe 2 O 3 content, depending on the type of acid
inorganic acid (Sulfuric acid and hydrochloric acid) activated bentonite clay is very efficient and shows satisfactory results. But there is a major disadvantage associated with its use. Fumes of hydrochloric acid or sulfuric acid are very dangerous for both the equipment and labor involved in

Raw clay was taken for experimentation, disintegrated on acid activation with sulfuric acid, which showed a particle size distribution. The montmorillonite and illite phases in the raw clay disappeared on acid activation and the activated clay, MIC(AA), showed with sodiumaluminumsilicate and beidellite phases apart from quartz (low) phase.
