Comparative study on thorium (İv) sorption onto sodic bentonite and magnetic bentonite

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 ...

Sorption Removal of Cs and Sr from Radioactive Wastewater by Modified Bentonite Clay

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.

Comparative Study of Laterite and Bentonite Based Organoclays: Implications of Hydrophobic Compounds Remediation from Aqueous Solutions

Four cost effective organoclays were synthesized, characterized, and studied for the sorption of hydrophobic compounds (edible oil/grease and hydrocarbon oil) from aqueous solutions. Organoclays were prepared by cation exchange reaction of lattice ions (present onto the surface of laterite and bentonite clay minerals) with two surfactants, hexadecyl trimethyl ammonium chloride (HDTMA-Cl) and te...
