Bentonite modified with ferrocyanides of Fe, Cu and CuK was tested for sorption of Cs137 and Sr-90 and proved to be highly selective for Cs; ferrocyanides of Cu and CuK are also good sorbents for Sr. Bentonite modified with hydroxides of Ti, Sn and Sb are good for Sr removal.

three-hundred and twenty 7-day-old ross 308-strain broiler chickens were fed diets containing 0 or 125 ppb aflatoxin b 1 (afb1) from 7 to 28 days of age. sodium bentonite (0.5%), yeast (saccharomyces cervisiae) 0.2%, hydrated sodium calcium aluminosilicate (hscas) (0.5%), ammonia (0.5%), formycine (0.1%), and toxiban (0.1%) were added to the basal diet, as fed basis to determine the effects of ...

Drilling waste is a problem that affects the environment, society, and health. However, rheological additive in drilling fluid source of generation waste. Hence, suitable became concern bored pile construction. Conventional bentonite has been replaced by usage polymer operations, this due to operational, environmental, economic aspects. Unlike bentonite, polyacrylamide (PAM) high molecular weig...

In this work, Ti-pillared bentonites were evaluated to remove ciprofloxacin (CIP) from the aqueous solution. Pillared sodium bentonite (BSP) and pillared calcium (BCP) prepared by means of sol–gel method using titanium tetraisopropoxide with calcination for 3 h at 500 °C. They characterized BET N2 adsorption, subjected X-ray diffraction Fourier transform infrared spectroscopy. The results show ...

The adverse effect of mineral dust on general health level of the population has been widely studied lately. The research interest has been mainly focused on the respiratory function of coal miners and workers exposed to silica and asbestos containing dust [1-3] because a significant increase in COPD independent of smoking has been observed [4-5]. Among the materials considered hazardous for wo...

This paper presents the effect of sisal fibers on the unconfined compressive strength of bentonite. The present study is aimed at determining the behavior of bentonite-lime-phosphogypsum reinforced with sisal fibers in a random manner. The sisal fiber content was varied from 0.5 to 2 %. The results indicated that the unconfined compressive strength of bentonite can be increased by the addition ...

Cement bentonite interactions need to be studied since they will occur in deep geological repositories.They are specifically relevant in the clay host rock reference concept. The reactivity of a Mg-homoionicFEBEX bentonite was studied at 60 oC in contact with a young cement water characterized by the leachingof alkaline hydroxides (K/Na 4/1 –OH, pH = 13.5 at 25 oC) and with an e...

Three-hundred and twenty 7-day-old Ross 308-strain broiler chickens were fed diets containing 0 or 125 ppb aflatoxin B 1 (AFB1) from 7 to 28 days of age. Sodium bentonite (0.5%), yeast (Saccharomyces cervisiae) 0.2%, hydrated sodium calcium aluminosilicate (HSCAS) (0.5%), ammonia (0.5%), formycine (0.1%), and toxiban (0.1%) were added to the basal diet, as fed basis to determine the effects of ...
