purification has become a topic of research. In this study, the use of bentonite clay modified by acid activation is proposed. Sulfuric acid, acetic acid (v-acid/w-clay ratio=20, 40 and 60%) and sulfuric/acetic mixtures (1:1 ratio) were used in the bentonite clay activation. The activated clays were used in the UMO
Acid activation technique was opted for modifying natural bentonite (NB) to enhance the adsorptive removal of CIP from water. The BET surface area analysis …

In the ironmaking process, the addition of an organic binder to replace a portion of bentonite has the potential to improve the performance of pellets. The interaction between original bentonite (OB) and organic binder was investigated. Results indicated that the micromorphology of organic composite bentonite (OCB) became porous and …
Abstract A study is performed of the effect the means of activation of bentonite-like clays (acidic, alkaline, combined) have on the adsorption characteristics of Fe3+ ions under static conditions. The mechanism of the acidic and alkaline activation of montmorillonite is identified and found to depend on the concentration of the activating …
Activated bentonites are low-cost acid catalysts used in several reactions. However, their application at an industrial scale is affected by the formation of colloidal suspensions when these …
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 ...
The only way to increase the low CEC of sandy tropical soils over the long term is to apply high CEC materials such as 2:1 clay minerals. Acid activated bentonite is used in Thailand in the vegetable oil industry during the clarification process. The waste bentonite is discarded afterwards. The aim of the study was to compare the effects of the addition of …
Bentonite is commonly used as a binder in iron ore pelletizing. Its primary phase is montmorillonite, characterized by a layered crystal structure capable of absorbing large amounts of water. ...

The presence of emerging pollutants such as hazardous chemicals, pharmaceuticals, pesticides, and endocrine-disrupting chemicals in water sources is a serious concern to the environment and human health. Thus, this study focused on exploring the interaction mechanisms between ciprofloxacin (CIP) (antibiotic) and clay (a …
Herein, the facile one step acid activation of bentonite derived functionalized adsorbent (AB) for the effective remediation of both ionic and non-ionic …
The fastest growing export markets for Bentonite of Oman between 2021 and 2022 were India ($192k), United Arab Emirates ($94.3k), and Qatar ($37.5k). Imports In 2022, …
Water treatment is of paramount importance to ensure the availability of clean and safe drinking water. In recent years, clay-based materials have gained significant attention as promising adsorbents for water treatment applications. This review provides a comprehensive analysis of different clay types and their surface adsorption properties …
Introduction. Ametryn is an ionic pesticide of the s-triazine family, with a chemical structure of the aromatic hexamer ring.The specific action of ametryn on plants is the inhibition of photosynthesis process, particularly at the photosystem II (PSII), leading to the blockage of electron transport by displacing plastoquinone from the unique binding …
The effects of activation parameters (time and temperature) on its physiochemical properties and its performance for the removal of sodium ions from water were investigated. Bentonite activated for 6 h at 300 °C showed a maximum specific surface area of 81.74 m 2 /g while the raw one showed 57.6 m 2 /g. However, the cation …
Bentonite activation was performed with three different concentration of H 2 SO 4 (3, 5, and 10 N), in order to investigate the impact of acid concentration on the surface area. Compared with natural bentonite, acid-activated bentonite displayed about 38–51% larger surface area (Table 1).
