A range of feed supplements, including antibiotics, have been commonly used in poultry production to improve health and productivity. Alternative methods are needed to suppress pathogen loads and maintain productivity. As an alternative to antibiotics use, we investigated the ability of biochar, bentonite and zeolite as separate 4% feed additives, to selectively remove pathogens without reducin...

The studies of the kinetics and isotherms adsorption of the Reactive Black 5 (RB5) onto bentonite clay were explored in a batch study in a laboratory. The maximum RB5 adsorption conditions of bentonite clay were optimized such as shaking speed (100 rpm), temperature (323 K), pH (10), contact time (40 min), initial dye concentration (170 mg·L−1), and particle size (177 μm). The adsorbent surface...

The article presents the distribution coefficient (Kd) values of 137Cs and 90Sr tracer radionuclides in solutions sodium calcium salts for a wide range commercially available inorganic sorbents: natural synthetic aluminosilicates, manganese, titanium zirconium oxyhydrates, phosphates, titanosilicates alkali metals, ferrocyanides transition metals. results were obtained using standard technique ...

-Treating NH4-bentonite with diazomethane results in methylation of adsorbed ammonium with the formation of the tetramethylammonium ion. This ion, which can be completely removed through ion exchange, is distinguished in the IR spectrum by a strong band at 1480 cm -1 due to CH3 group bending vibrations. X-ray diffractograms, CEC, and surface area of the clay are not modified by treatment with d...

background: aflatoxin-contaminated feed cause mortality, suppression of the immune system, reduced growth rates and losses in feed efficiency. an experiment was conducted to evaluate the ability of different levels of sodium bentonite (sb), silybummarianum seeds (sms) and their combination for reducing the adverse effects of aflatoxin b1 (afb1) in broiler chicks. materials and methods: 224 male...

The present work is aimed at studying the adsorption capacity of powdered Fuller’s earth for the removal of ferri/ferrous impurities found in commercial grade sodium sulphide. The latter is not suitable for the manufacture of pharmaceutical grade chemicals and dye chemicals. The author has carried out experiments taking different dosage of powdered Fuller’s earth as an adsorbent in the aqueous ...

montmorillonite is the major mineral of bentonite with many applications in industrial fields but some impurities decreases the quality of the bentonite. the main objective of this study was to investigate the suitable method for purification of ghaen mine bentonite. a combination of methods was considered including wet sieving and sedimentation, centrifuge and ultrasound. the efficiency of pur...
