ZEOLITE-BEARING BENTONITES

Coupled chemical-hydraulic-mechanical behaviour of bentonites

Removal of Pesticide Residues from Water by Organo-bentonites

Contamination of water resources with pesticides residues becomes a pressing problem in Gaza due to the frequent application of pesticides in the intensive agricultural system. This study tests the potential of using organo-bentonite as a porous material to remove bromoxynil residues from contaminated water. Bentonite surfaces were activated for removal of bromoxynil residues from water by simp...

Characterisation of northern Patagonian bentonites for pharmaceutical uses

This paper evaluates the suitability of some smectite-rich samples from northern Patagonia (Argentina) for pharmaceutical use. The clays must comply with some general features before considering their use in pharmacy, including high mineral and chemical purity and the absence of microbial pathogens. Specific characteristics such as sediment volume, swelling power and gel formation are also impo...

Zeolite Research

A new anti-diarrheic drug for humans has been developed based on the physical and chemical properties of the purified natural clinoptilolite NZ. A series of physical, chemical, technological, pharmacological, microbiological, and clinical studies were successfully conducted to meet the requirements of the Cuban Drug Quality Agency. The most important results concerning the properties and biolog...

Zeolite potentials

A double-blind cross-over study was performed to evaluate the inhibitory activity of silver zeolite (SZ) mouthrinse on plaque formation. Eleven dental students participated in this study. SZ mouthrinse was prepared by suspending SZ powder into phosphate-buffered saline (PBS) at a concentration of 3% (w/w). Type-A zeolite was used as a placebo. Before the experiment, the subjects were rendered p...
