Feb 04, 2019 · Raw bentonite (RB) was chemically modified by citric acid (CA) to obtain a lowcost and environmentfriendly citric acid incorporated bentonite (CAB) adsorbent, which was applied for the adsorptive removal of Congo Red (CR). The effect of adsorbent dosage, contact time, ionic strength, surfactant, and pH on adsorption was investigated.

Nov 17, 2012 · Activation of Iraqi Bentonite Powder with H SO and its .. work was to enhance the bleaching activity of Iraqi bentonite after activation by sulfuric acid. .Local bentonite clay was first ground . to ASTM method D2854 83. 226 . »More detailed

In this study, a bentonite clay sample from Mendoza (Argentine) was activated in different concentrations (4 N and 8 N) through the use of sulphuric and hydrochloric acid. To verify the influence of concentrations and the kind of acid utilized in the clay activation, it was utilized techniques of Xray diffraction, thermogravimetric and ...

ABSTRACT. Two bentonite clays with different mineralogical compositions from Mendoza, Argentine, were activated with H 2 SO 4 solutions of 4 and 8 N at 90ºC for hours. This treatment affected clay structural properties, as was shown by thermogravimetry, infrared spectrometry and chemical analysis.

Bentonite has been successfully activated using hydrochloric acid, as shown by FTIR, XRD, and TGA studies, in addition to an increase in its surface area. Acid activated bentonite shows a great potential for the removal of heavy metal ions and phenolic compounds pollutants. Results show that percentage uptakes exceed 99% for Zn, Fe, and Mn ions.

Apr 20, 1995 · It is seen from the results in Table 8 that the activated bentonite according to the present invention exhibits high swelling power even in an 1N aqueous sulfuric acid solution. Then, swelling power of the same samples in a aqueous sodium hydroxide solution was measured in the same manner as described above.

Apr 03, 2018 · Clay E is a swelling bentonite (Clay Spur) of the western type and, as is typical, changes relatively little upon acid activation. As is obvious, surface area can be made to improve quite dramatically for the nonswelling bentonltes, but in all cases it does pass through a maximum beyond which additional acid treatment actually reduces surface ...

A process for making acidactivated bleaching earth from certain naturally occurring mixtures of calcium bentonite and attapulgite clay. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clayacid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower ...

An activation of natural clay has been developed. Activation was applied by refluxing the natural bentonite in variation of the sulfuric acid concentration and calcination time of pillared bentonite (PLC). Calcination was applied using oven in microwave 2,45 GHz. Determination of acidity was applied by measuring the amount of adsorbed ammonia and pyridine.

The search for inexpensive and environmentally friendly alternatives for used motor oil (UMO) purifiion has become a topic of research. In this study, the use of bentonite clay modified by acid activation is proposed. Sulfuric acid, acetic acid (vacid/wclay ratio=20, 40 and 60%) and sulfuric/acetic mixtures (1:1 ratio) were used in the bentonite clay activation.

Dec 31, 2015 · Prrenjas clay mineral is found in southeast Albania and has a high content on bentonite. The influence of the sulphuric acid activation on the composition, structure and surface properties of Prrenjas clay mineral is investigated in this study by means of elemental chemical analysis, XRay Diffractometry, IR Spectroscopy and gas adsorptiondesorption measurement.
