Jan 30, 2014 Chemical composition of bentonite may undergo change if when given treatment with ion exchange or by activation. Activation that is often used is thermal activation and chemical activation, in this study used activator is 6% HCl. Bentonite is used as the sample obtained in five villages in the district. Sample preparation is done by the process of drying with sunlight and oven, then puree and

Apr 15, 2008 Activation of bentonite by acid is an important step for adsorption of some impurities by active clay . 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 .

The surface characteristics of AB were examined by the nitrogen adsorption-desorp

Due to the ion exchange hysteresis, activated bentonite shows a post-rise time-swell relationship different than the sigmoid-shaped time-swell curves of typical bentonites. That is, a greater part of swelling strain develops after the completion of primary swelling strain. At an optimal amount of 1% Na2CO3 in weight, the maximum swelling strain

Jan 01, 2018 During the acid activation of bentonite, a decrease in the intensity of stretching and bending bands (a characteristic of octahedral sheet for Al-Al-OH) is observed at 1650 [cm.sup.-1], which reflects the leaching of octahedral cations, such as [Al.sup.3+] and [Mg.sup.2+], from the bentonite structure, thus indicating the destruction of the

ALTERNATIVE METHOD OF THE ACTIVATION PROCESS

activated bentonite has a molar ratio of SiO2 and Al2O3 between 6 - 9. All methods resulted in expected molar ratio, but the 2 weeks settlement process without heating provided more significant result which means it performed energy saving compared to other methods. Keywords: activation, bentonite, molar ratio, settlement INTRODUCTION
