A comparison is made of tests for thyroglobulin antibody, using gel diffusion, electroprecipitin, bentonite flocculation, tanned red cell agglutination, and latex slide agglutination techniques on sera from cases of Hashimoto's disease and other thyroid disorders. Any increase in gamma globulin was also noted from the serum electrophoretic pattern. The gel diffusion and electroprecipitin tests ...

In this study, the main objective is the preparation and the characterization of a modified Algerian bentonite based adsorbent by intercalation with hexadecyltrimethylammonium bromide (HDTMA). Natural and modified bentonites were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The X-ray results indicate that the geometry of the int...

Sodium bentonite was subjected to the effect of two new homologue series of chlorides (alcoxymethyl) dimethyloctyloamonium chlorides and 3-alcoxymethyl-1-octylimidazole chlorides with the hydrophobic substituents of the same length. Morphology of the obtained modified bentonite was studied under scanning electron microscope [SEM] and the degree of adsorption of the ammonium salts was determined...

removal of typical contaminants like aromatic amines (e.g. 1-naphthalen amine, diphenyl amine, aniline, 2 and 6-dimethyl pyridine) from water during one-stage process is a method to purify water wherein organic contaminants get extracted from water by bentonite. in this study the effects of ph, stirring time, stirring speed, bentonite mass and bentonite size (mesh) were investigated. also, the ...

this experiment was conducted with broiler chickens to evaluate the effects of high and low swelling bentonite (natural and processed by cuso4) supplementation in diets on performance and carcass traits. a total of 300 day-old aryan broiler’s chicks were used in a completely randomized design with 5 dietary treatments. six pen replicates of 10 chicks were assigned to each of five dietary treatm...

Movement of NH(4)(+) below animal waste lagoons is generally a function of the whole-lagoon seepage rate, soil mineralogy, cations in the lagoon liquor, and selectivity for NH(4)(+) on the soil-exchange sites. Binary exchange reactions (Ca(2+)-K(+), Ca(2+)-NH(4)(+), and K(+)-NH(4)(+)) were conducted on two soils from the Great Plains and with combinations of these soils with bentonite or zeolit...
