The interaction between bentonite and tylosin was investigated in broiler chickens, based on pharmacokinetic characteristics obtained in vivo. Simultaneous oral administration of bentonite and tylosin significantly lowered plasma levels of tylosin and reduced the area under the plasma concentration-time curve (AUC(0-inf)), maximal plasma concentration (C(max)), time to maximal plasma concentrat...

In the treatment of industrial polluted sites and construction landfill sites, anti-pollution barriers are usually used to prevent diffusion pollutants. this paper, adsorption characteristics Zn ions by rock-bentonite barrier were observed means static equilibrium dynamic tests. The experimental results showed that stone chips—bentonite was close nonlinear Freundlich Langmuir models. When conce...

Bentonite is a native, colloidal, hydrated aluminum silicate. It occurs as a very fine, odorless, pale buff or cream-colored powder, free from grit, and has a slightly earthy taste. Although it is insoluble in water, it swells to approximately 12 times its volume when added to water. Bentonite magma is prepared by adding 50 gm. of bentonite to a sufficient quantity of purified water to make 1 l...

The main goal of this study is studying the improvement engineering properties soil mass. These are shear strength and maximum dry density which effect on foundations structures their stability. cohesionless can be given some cohesion by rearrangement particles decrease voids between adding fine them increase density, then required improved. chemical combinations due to additives also generate ...

This study investigated the combined effect of temperature and single-species salt solutions on geotechnical properties (swell index and liquid limit) and hydraulic conductivity of bentonite applying different cation types, concentrations, and temperatures. Results showed that both the swell index and the liquid limit decreased with an increase in salt concentration irrespective of the type of ...

Bentonite with its unique structural properties is a valuable material for environmental application. Its sorption properties are usually improved by the different ways of modification. In this work, the special sedimentation method was used for the treatment of the natural bentonite to obtain monomineral fraction of montmorillonite. The modification by iron oxide particles was used with the ai...

The present study compared the performance of soldier pile and concrete bearing pad anchored wall facings. Using Abaqus finite element software, two case studies have been precisely represented for the facing designs and effects of the parameters of soil type, spacing of anchors and facings, surcharge and facing sizes were investigated. The analysis results indicate that the soldier pile method...

An intensive study has been made to see the performance of the different liner materials with bentonite on the removal efficiency of Cu(II) and Zn(II) from industrial leachate. An artificial neural network (ANN) was used to display the significant levels of the analyzed liner materials on the removal efficiency. The statistical analysis proves that the effect of natural zeolite was significant ...

Bentonitic material from South Aswan, Egypt was evaluated in terms of mineral-ogy and chemical composition as bleaching clay in refining of transformer oil before and after acid activation and thermal treatment followed by acid leaching using HCl and H2SO4 for different contact times. Structural modification and refining power of bento-nite were investigated during modification by means of X-ra...
