Characterization of Organo-Modified Bentonite Sorbents: The Effect of Modification Conditions on Adsorption Performance
(Elsevier Science, 2014-09)
The organic modification of a natural bentonite was evaluated using two methods: exchanging the interlayer cations by hexadecyltrimethylammonium (HDTMA) and grafting with vinyltrimethoxysilane (VTMS) and -methacryloyloxy ...
Adsorption of Cu ions onto a 1.10 phenanthroline-grafted Brazilian bentonite
(2003-02-01)
The grafting, by chemical adsorption, of molecular 1.10-phenanthroline (OP) onto some Brazilian bentonite (montmorillonites) was studied to improve their adsorptive capacities to remove Cu ions from synthetic wastewater. ...
Extended and local structural characterization of a natural and 800 °C fired Na-montmorillonite–Patagonian bentonite by XRD and Al/Si XANES
(Elsevier Science, 2017-03)
A structural characterization of a Patagonian bentonite and its corresponding heating product (800 °C) was carried out. The nature of aluminum and silicon atoms was investigated using Al and Si K-XANES spectroscopy and ...
Adsorption of anionic dyes monoazo and diazo using organo-bentonite
(Springer, 2019-01)
Adsorption of orangeand yellow dyes, containing mono- and di-azoic groups, respectively, werestudied by the use of a natural and organo-bentonite, which was obtained bytreatment with hexadecyl-trimethyl-ammonium bromide. ...
Porous modified bentonite as efficient and selective catalyst in the synthesis of 1,5-benzodiazepines
(Springer, 2013-03-01)
The synthesis of 1,5 benzodiazepine using natural and modified Argentinean bentonite (pillared layered clay and porous clay heterostructure) as catalysts through a condensation reaction between o-phenylenediamine (o-PDA) ...
Ciprofloxacin Removal Using Pillared Clays
(2023)
In this work, Ti-pillared bentonites were evaluated to remove ciprofloxacin (CIP) from
the aqueous solution. Pillared sodium bentonite (BSP) and pillared calcium bentonite (BCP) were
prepared by means of the sol–gel method ...
