This study aimed to develop controlled release formulation of Thiabendazole for reduced contaminations to soil water and agricultural produces. The idea behind this work was based on changing the ionization status of Thiabendazole molecule throughout pH changes to become a cation then adsorbing it to bentonite clay surfaces. Equilibrium concentrations of Thiabendazole in the adsorption solution...

Clay feed additives have been increasingly incorporated into animal diets to prevent aflatoxicosis. Due to the nonselective nature of the binding interaction, many important components of the diets could also be made unavailable because of these feed additives. The anticoccidial monensin (MON) could also be sequestered by these clays. The use of sodium bentonite (Na-B) from a mine in the provin...

background and objectives: biofilms are structural communities of bacterial cells enshrined in a self produced polymeric matrix. the studies on biofilm formation of pasteurella multocida have become imperative since it is a respiratory pathogen and its biofilm mode could possibly be one of its virulence factors for survival inside a host. the present study describes a biofilm assay for p. multo...

Bentonite is a mixture of clay and non-clay minerals. Montmorillonite mineral dominant in bentonite. Silica alumina bond the crystal structure montmorillonite. Therefore, they cannot contribute to pozzolanic reaction. Heat treatment bentonite leads destruction montmorillonite converting silica reactive phases. Thermally activated (TAB) relatively low pozzolan when used as partial replacement Po...

Clay slurries are both ubiquitous and essential in the oil exploration industry, most commonly employed as drilling fluids. Due to its natural abundance, bentonite clay is often the...

The functionalization of bentonite by intercalation of surfactants dodecylamine, hexadecylamine, octadecylamine, and the octadecyltrimethylammonium cation is described. Products are characterized by elemental analysis, thermal analysis, FT–IR spectra, and powder X-ray diffraction analysis. Laminar amine-clay nanocomposites contain about one mol amine per (Si,Al)4 clay unit, while the cationic s...

Researches on feeding with Biolekks premix and bentonite clay to pigs for fattening were conducted. It was established that the tested additives have beneficial effect on animals. However the greatest effect was obtained with combined feeding. So the live weight of pigs increased by 5.2% (at P≤0.999), surviving – by 4%, the level of profitability of pork production – by 18.6%, also revealed was...

Microalga is the only feedstock that has the theoretical potential to completely replace the energy requirements derived from fossil fuels. However, commercialization of this potential source for fuel applications is hampered due to many technical challenges with harvesting of biomass being the most energy intensive process among them. The fresh water microalgal species, Scenedesmus abundans, h...

Abstraet--Jordanian natural kaolin and bentonite show good catalytic activity towards debutylating 2tert-butylphenol, and varying debutylation vs. isomerization selectivity after acid activation. The resulting catalytic activity of these samples is dependent on the acid employed for activation; the samples treated with acetic acid showed relatively low conversions, whereas those treated with hy...

Sand–clay mixtures can be encountered in both natural soils (e.g., residual soils, clay deposits and clinosols) artificial fills. The method of utilising biopolymers ground improvement for sand–clay has emerged recently. However, a full understanding the strengthening effect biopolymer-treated not yet been achieved due to limited number relevant studies. In this study, xanthan gum (XG), as one ...
