Sorption isotherm and kinetic modeling of aniline on Cr-bentonite.

In this paper, the sorption characteristics of aniline on Cr-bentonite prepared using synthetic wastewater containing chromium was investigated in a batch system at 30 degrees C. The effects of relevant parameters, such as pH value of solution, adsorbent dosage and initial aniline concentration were examined. The experimental data were analyzed by the Langmuir and Freundlich, and Temkin models ...

Sealing Properties of Bentonite Suspensions*

Sealing with waterborne clays is a rapid and low cost method of controlling seepage through porous media whenever the clay source is within economical shipping distance of the sealing site. But more must be learned about this method of sealing before it can be fully utilized. Water impedance of waterborne bentonites, as measured by water loss in the filter press test, was correlated with their ...

Biofilm formation of Pasteurella multocida on bentonite clay

BACKGROUND AND OBJECTIVES Biofilms are structural communities of bacterial cells enshrined in a self produced polymeric matrix. The studies on biofilm formation of Pasteurella multocida have become imperative since it is a respiratory pathogen and its biofilm mode could possibly be one of its virulence factors for survival inside a host. The present study describes a biofilm assay for P. multoc...

“Effect of bentonite treatment of grape juice on yeast fermentation”

• Bentonite fining is widely used to increase the protein stability of a wine. Some authors have proposed treatment of the juice itself, rather than the wine, to enhance fermentation performance and flavor, and increase stability. Some authors have reported that this practice yields stable wines not requiring further fining, whereas others have found no increase in stability when treating the j...
