Removal of Pb(II) ions from aqueous solutions using natural and HDTMA-modified bentonite and kaolin clays

open access: yesHeliyon
This work focused on the removal of Pb(II) from aqueous solution using kaolin and bentonite clays modified with hexadecyl trimethyl ammonium bromide (HDTMA). The clays were characterized using a zetasizer, scanning electron microscopy (SEM), powder X-ray

Effect of dehydroxylation/amorphization degree of bentonite on the microstructure, thermal stability, and mechanical strength of basalt epoxy composites

open access: yesJournal of Materials Research and Technology, 2023
Calcination of smectite clays such as bentonite is tricky due to their 2:1 aluminosilicate structure. Low calcination temperature has minimal effect on the dehydroxylation, specific surface area (SSA), and crystalline nature of bentonite clays whereas ...

Thermochemical Treatment of Nigerian Raw Clays for Oil and Gas Drilling Operations

open access: yesChemEngineering, 2023
Sodium-based bentonite is used for drilling operations because of its high swelling capacity. This type of bentonite clay is not sourced locally in many oil- and gas-producing nations.

Bentonite Clay Modified Concrete

open access: yes, 2022
Replacing cement with pozzolanic materials to some extent in construction is found to be one of the sustainable approaches in the construction industry. Pozzolanic materials of industrial origin like fly ash and Ground Granulated Blast furnace Slag will have to be replaced with natural pozzolanic materials once the world moves towards renewable energy ...

Biogas Upgrading Using Cation-Exchanged Bentonite Clay

open access: yesIndustrial & Engineering Chemistry Research, 2023
The separation of CH4 and CO2 in biogas, known as biogas upgrading, can produce two valuable gas products and prevent greenhouse gas emissions. One method hereto is (vacuum-)pressure swing adsorption that involves the selective adsorption of CO2 on a sorbent.

STUDY OF THERMAL AND ACID STABILITY OF BENTONITE CLAY

open access: yesIndonesian Journal of Chemistry, 2010
The thermal and acid stability of the bentonite clays (Na- and Ca-bentonite) have been tested. The thermal stability testing has been carried out by heating 5 gram of the clays  for five hours at 200, 300 and 500 °C respectively, meanwhile acid stability
