The adsorption of contaminants plays an important role in the process of their elimination from a polluted environment. This work describes the issue of loading environment with lead Pb(II) and the resulting negative impact it has on plants and living organisms. It also focuses on bentonite as a natural adsorbent and on the adsorption process of Pb(II) ions on the mixture of bentonite and botto...

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...

LUSI mud obtained from the mud volcano in Sidoarjo, Indonesia, is a viable aluminosilicate material to be utilized as pozzolanic material. LUSI is an abbreviation of the local name of the mud, i.e., Lumpur Sidoarjo, meaning Sidoarjo mud. This paper reports the results of an investigation to assess the pozzolanic activity of LUSI mud, especially in semi high volume pozzolanic mortar. In this cas...

-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. ...

A study was conducted to determine the effect of ration containing differently treated Sodium Bentonite on broiler performance. 280 day-old broiler chicks were randomly allocated to 7 experimental groups designated as A (Control), B & C (Sodium Bentonite 0.5% & 1.0% respectively), D & E (Sodium Bentonite + Gention Violet 0.5% & 1.0% respectively), F & G (Sodium Bentonite + Acetic Acid 0.5% & 1....

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...

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...
