Sorption of Pb(II), Cd(II), and Ni(II) Toxic Metal Ions by Alginate-Bentonite
Toxic metals Alginate Bentonite Wastewater
2013/3/9
The sorption of Pb(II), Cd(II), and Ni(II) toxic metal ions from aqueous solution by composite alginate-bentonite and alginate was investigated. The affinity and sorption capacity of the toxic metal i...
Removal of Phosphate from Aqueous Solution with Modified Bentonite
adsorption phosphate sawdust bentonite
2009/11/13
Bentonite combined with sawdust and other metallic compounds was used to remove phosphate from aqueous solutions in this study. The adsorption characteristics of phosphate on the modified bentonite we...
Electrical Spectroscopy of Kaolin and Bentonite Slurries
bentonite contamination dielectric permittivity electrical conductivity kaolin, slurry
2009/10/13
The electrical conductivity and dielectric permittivity of clay-water systems were used to characterize the physicochemical state of kaolin and bentonite-water systems. The dielectric permittivity and...
Adsorption of 4-Toluene Sulfonic Acid on Modified Bentonite : Optimization by Response Surface Methodology
Adsorption Smectite Organobentonite Response surface methodology
2009/10/12
Adsorption of 4-toluene sulfonic acid (4-TSA) onto modi ed bentonite (ODTMA-bentonite) was carried out. ODTMA-bentonite was synthesized by placing quaternary ammonium surfactant (octadecyltrimethyl am...
Modeling the competition between solid solution formation and cation exchange on the retardation of aqueous radium in an idealized bentonite column
reactive transport solid solutions cation exchange bentonite radioactive waste repository montmorillonite OpenGeoSys GEM-Selector
2017/8/9
Clays and clay rocks are considered viable geotechnical barriers in radioactive waste disposal. One reason for this is the propensity for cation exchange reactions in clay minerals to retard the migra...
