Ž . The absorption, metabolism, and excretion of dietary aflatoxin B AFB by trout given 1 1 different diets were compared. Fish were fed one of two diets: an AFB contaminated basal diet or 1 the contaminated basal diet with 2% sodium bentonite. Urine, feces, and gill excretions were collected and analyzed separately over a 7-day test period. On completion of the feeding trials, the fish were eu...

BACKGROUND From old times, the human kind has used clays, externally or internally, for maintaining body health or treating some diseases. Meanwhile there are few scientific articles reviewing the beneficial effects of clays on body function. Bentonite clay is one of the available clays in nature, used as traditional habits, and remedies in many cultures. METHODS These articles explored among...

BACKGROUND Fourier transform infrared spectroscopy (FTIR) has been used as analytical tool in chemistry for many years. In addition, FTIR can also be applied as a rapid and non-invasive method to detect and identify microorganisms. The specific and fingerprint-like spectra allow - under optimal conditions - discrimination down to the species level. The aim of this study was to develop a fast an...

Compacted and water saturated bentonite will be used as an engineered barrier in deep geological repositories for radioactive waste in many countries. Due to the high dose rate of ionizing radiation outside the canisters holding the nuclear waste, radiolysis of the interlayer and pore water in the compacted bentonite is unavoidable. Upon reaction with the oxidizing and reducing species formed b...

Compacted bentonite–sand (B–S) and bentonite–fly ash (B–FA) are established combinations for the construction of landfill liners. This study determined upper lower bounds equilibrium hydraulic conductivity (k eq ) amended B under extended duration flow. The k constant-volume flow condition differed from free-swelling by more than two orders magnitude due to difference in geomaterial interaction...

The objective of this study is to describe the mineralogical composition and chemical properties Ora?u Nou bentonite, from northwestern Romania. For determinations, following were used: X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FR-IR), thermogravimetric analysis, scanning electron microscopy coupled with energy-dispersive (SEM-EDX). compositions physical bentonites bento...

A new serological technique of diagnosing human hydatid disease, employing polystyrene latex particles coated with hydatid cyst fluid, and a modified technique using bentonite particles are described. Comparison of the latex test with the complement-fixation test performed on 102 sera has shown a total agreement of 98% and an agreement of 93.1% in the positive specimens. The bentonite test and ...

Toxoplasmosis is a common disease among human and livestock with a worldwide distribution. This disease will be generated by a unicellular parasite called toxoplasmosis Gondii. The disease usually is diagnosed in laboratory through several methods such as; ELISA, Immunofluorescence and Chemo luminescence. The mentioned methods have sufficient sensitivity and trait, but since they are need to us...

Vegetable oil is one of the basic food items which is consumed by almost every human being in this universe. Therefore quality of vegetable oil should be good enough so that it accounts for healthy life. In vegetable oil manufacturing there are four major steps involved which are neutralization, degumming, bleaching and deodorization. Among these steps bleaching is the very important and critic...

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...
