Clark, D. G. (1970). Brit. J. industr. Med., 27, 186-188. Inhibition of the absorption of paraquat from the gastrointestinal tract by adsorbents. The efficacy of the oral administration of adsorbents Kaolin, Decalso, Amberlite, Bentonite and Fuller's Earth in preventing the toxic actions ofingested paraquat (1,1'-dimethyl-4,4'-dipyridylium) has been assessed using rats and cats. Only Bentonite ...

This article used bentonite impregnated with titanium and silver, respectively, as photocatalyst, to degrade methylene blue (MB) under conditions of MB solutions exposed to sodium lamp and sunlight. Due to the semi-conducting properties of synthesized bentonite catalysts, when exposed to sodium lamp and sunlight, catalyst particles are excited for photocatalysis to achieve decolourization. Afte...

The removal of potentially harmful radioactive waste from the anthroposphere will require disposal in geological repositories, designs which often favour inclusion a clay backfill or engineered barrier around waste. Bentonite is proposed as this and understanding its long-term performance behaviour vital establishing safety case for usage. There are many different compositions bentonite that ex...

-Infrared spectroscopic, X-ray powder diffraction, diffuse reflectance, and electron-spin resonance examination of homoionic bentonite from Sardinia treated with diazomethane indicates that polymethylene was formed in the interlayer position. Polymerization can be attributed to the acidic properties of the residual water in the interlamellar space, depending on the nature of the exchanged ion. ...

In an effort to characterize individual eruptive phases and events, 86 isolated mare deposits (ponds) in the lunar South Pole-Aitken and Orientale regions were analyzed to obtain information on areas, volumes, and other characteristics. Deposits likely to represent single eruptive episodes have area mean values of-2000 km 2 in the South Pole-Aitken Basin and -1100 km 2 in the Orientale Basin. P...

The aim of the present study was to evaluate the effect of zinc as feed additive on some the blood plasma traits of males and females of broiler breeder chickens. A total 132 (96 females and 36 males) of Cobb 500 broiler breeder chickens, 45 weeks old were used in this study. These birds were randomly distributed into four dietary treatment groups with three replicates each. Each treatment grou...

in order to evaluate the effect of feeding different levels of vermi-humus supplement (as a source of humic acid) on the performance of broiler chickens an experiment was conducted using 240 broiler chickens (ross 308) in a completely randomized design by four treatments (vermi-humus levels of 0, 0.5, 1 and 1.5 percent) and five replicates of 12 chickens per each for 42 day. the experimental tr...

The passive haemagglutination and bentonite flocculation tests were compared for detecting plant viruses, using antibody-sensitized tanned red cells or bentonite particles. Parsnip yellow fleck, raspberry ringspot, turnip yellow mosaic, narcissus mosaic, potato X and tobacco rattle viruses were detected by both tests in purified preparations and, where studied, in crude plant extracts. The high...
