Resumen
The requirements for drilling bentonites are tightening due to ever-increasing demands for petroleum resources, coupled with cost and reaction technology constraints. In addition to raising the risk of drilling, bentonite’s poor performance also raises the possibility of safety incidents and significant financial losses. Organically modified bentonites effectively reduce the consumption of drilling fluids, conserve resources, and lessen environmental effects. This paper aims to provide an overview of the several organic modification methods of bentonite for drilling fluids. It also evaluates t

In a previous paper, adsorption isotherms of benzene vapor on natural bentonite from Ginovci, Macedonia, and forms acid activated with 10% and 15% solutions of hydrochloric were interpreted by means of the Dubinin-Radushkevich-Stoeckli and Dubinin-Astakhov equations; the investigation has been continued with bentonites acid activated with 10% and 15% solutions of sulfuric acid where X-ray analysis indicates smaller structural changes.

Resumen
Activated Bentonits of Sulfatic Acid as Adsorben in Purchase of Used Lubricants Recycling of used lubricating oil is one of the alternatives in the framework of efficiency, saving oil consumption, and reducing pollution. One effort to purify used lubricating oil is to separate impurities through the adsorption method. The adsorbent that can be used is bentonite. Activation of bentonite using acid will produce adsorbent with an active side and greater surface acidity so that the adsorption ability is higher than before activated. Characteristics of lubricating oil produced are: kinematic viscos

Resumen
Abstract Pertechnetate anion sorption was investigated on modified bentonites. Mn-, Cr-, Sn-bentonites were prepared by ion exchange process to sorb radioactive pertechnetate ions. In the case of Mn-, Cr-bentonite the sorb amount of metal ion was 70–90% of the cation exchange capacity of the bentonite which is expected. Interestingly in the case of Sn-bentonite this amount was 1.42 times higher than the cation exchange capacity. On Mn-bentonite the sorption was 35% at pH 5. The removal of pertechnetate ions was 100% on Cr-, Sn-bentonites and the significant sorption was achieved below 650 mV/S

A Nigerian, and a Liberian Bentonite has been studied. The two Bentonite samples which were obtained from the natural geological source were critically studied. The study covered the physical, chemical, and the foundry properties of the two Bentonites. The sieve analysis of the sand used for the investigation of the foundry properties was also carried out. The result showed that the Liberian Bentonite is a sodium based Bentonite, with a Na<sub>2</sub>O content of 1.91% with only traces of CaO. The Bentonite equally had a swelling index of 15, and green shear and compression strengths of 6.90KN

Resumen
A new approach to production of organomodified bentonites is offered. Bentonites are consecutively treated with inorganic polyelectrolyte (sodium silicate solution) and quaternary ammonium salts, as a result exfoliated organoclays are obtained. An ejector set up has been used for treatment of natural bentonites. Samples of activated bentonites treated in the ejector set up with sodium silicate solution (up to 21 g of sodium silicate per 100 g of bentonite) were prepared. Structure of the obtained bentonite and organoclay samples was established by X-ray diffraction analysis. It has been shown

Resumen
Deep geological disposal is a method of managing high level, long-­‐lived nuclear waste. It is a concept that many countries are exploring for the possibility of managing nuclear waste generated from power production. For deep geological disposal to be viable then areas where problems may surface have to be explored. Bentonite clay has been proposed as the material to be used for the backfill of the repositories. Its swelling properties ensure that it will expand to plug the bore holes that will be made for the waste, its impermeable nature restricts contact between groundwater and the waste p

One kind of heavy metal that comes from industrial waste is Cr (VI), which is obtained from steel, textile, tanning, photography, dyes, explosives, matches, and fuel mobilization waste.

This study aims to investigate the effects of varying adsorbent doses on the properties, % removal, isotherms, and kinetics of adsorption of Cr (VI) from aqueous solution.

Resumen
Bentonite is one of the safety-critical components of the engineered barrier system for the disposal concepts developed for many types of radioactive waste. However, bentonite — especially the swelling clay component that contributes to its essential barrier functions — is unstable at high pH. To date, results from laboratory tests on bentonite degradation have been ambiguous as the reaction rates are so slow as to be difficult to observe. As such, a key goal in this project is to examine the reaction of natural bentonites in contact with natural hyperalkaline groundwaters to determine if any

Resumen
The self-sealing function of the clearances between buffer material and overpack and tunnel wall or disposal pit wall and between backfill material and tunnel wall is expected for bentonite which will be used as buffer material and part of the backfill material. In this study, an analytical theory on the clearance filling performance for both materials was constructed. Volumetric swelling ratio of bentonite (Rvs) and maximum clearance ratio that bentonite can fill clearance (Rsmax) were calculated against dry density for different montmorillonite and silica sand contents of bentonites in disti
