Sodium bentonite can bind to dietary pigment and decreases yolk color scale. Sodium bentonite is one of the main parts of Formycine® Gold, the effect of different levels of Formycine® Gold and dietary pigment on egg quality, egg yolk color and performance criteria of laying hens from 26 to 34 week of age were studied. One hundred ninety two Hy-Line hens were divided into 24 groups of 8 birds ea...

Wine clarity is a critical aspect in the commercialization of white wines. The formation wine haze can be attributed to aggregation and precipitation heat-unstable proteins. Bentonite fining commonly used method winemaking for protein removal, but it responsible loss volume quality. Dicarboxymethyl cellulose (DCMC) was developed as potential alternative bentonite. Water-insoluble DCMC prepared ...

A class of heterogeneous catalysts based on commercial bentonite from natural origin, containing at least 80 wt% of montmorillonite clay, was designed to transform selectively and under mild conditions toxic organosulfur and organophosphorus chemical warfare agents into non-noxious products with a reduced impact on health and environment. The bentonite from the natural origin was modified by in...

Rats were offered ad libitum zinc in twice the level of the standard diet (23 mg/kg diet), and bentonite (2% additive) for 28 d, together with traces of zinc chloride (labelled with zinc-65) given intragastrically. Results provided evidence that bentonite increased the body retention of zinc in comparison to the diet without this agent. Furthermore, the addition of bentonite did not influence f...

The performance assessment of a geological repository for radioactive waste requires quantifying the geochemical evolution of the bentonite engineered barrier. This barrier will be exposed to coupled thermal (T), hydrodynamic (H), mechanical (M) and chemical (C) processes. This paper presents a coupled THC model of the FEBEX (Full-scale Engineered Barrier EXperiment) in situ test which accounts...

Experiments were conducted to determine the effect of bentonite and nonnutritive dietary polymers on toxicity and metabolism of T-2 toxin in rats. Male weanling rats were fed diets containing 5% bentonite, anion exchange resin, cation exchange resin or vermiculite-hydrobiotite. Each diet was fed with and without 3 micrograms T-2 toxin/g of feed for 2 wk. Bentonite and anion exchange resin were ...

Most safety cases for the deep geological disposal of radioactive waste are reliant on the swelling of bentonite in the engineered barrier system as it saturates with groundwater. Assurance of safety therefore requires effective monitoring of bentonite saturation. The timeand fluid-dependent corrosion of synthetic magnets embedded in bentonite is demonstrated here to provide a novel and passive...

Contamination of water resources with pesticides residues becomes a pressing problem in Gaza due to the frequent application of pesticides in the intensive agricultural system. This study tests the potential of using organo-bentonite as a porous material to remove bromoxynil residues from contaminated water. Bentonite surfaces were activated for removal of bromoxynil residues from water by simp...

Bentonite clay collected from Jabal Umm Ali area NE of Khartoum (Sudan) was characterized by X-ray diffraction (XRD). It was then purified by treatment with distilled water and activated with sulfuric acid at 90 oC for 3.5 hrs. XRD indicated modification of activated bentonite with enhanced surface area. Several cations were removed from octahedral sheet (Mg, Al, and Fe). Increasing the acid co...
