Paramagnetic pillared bentonites - The new digestive tract MRI contrast agents
(Elsevier, 2010)
The availability of sophisticated diagnostic methods such as MRI has contributed to the increased use of imaging technologies in therapy and diagnostic studies. However, gastrointestinal tract MRI generally shows poor ...
Mixed pillared bentonite for electrooxidation of phenol
(Elsevier, 2010)
Bentonite was pillared with Al, Al-Cu, Al-Fe or Al-Co poly(hydroxo metal) cations for electrochemical oxidation of phenol in acidic solution. Multisweep cyclic voltammetry was applied to analyze the behavior of the bentonite ...
Modeling and optimization process parameters of acid activation of bentonite by response surface methodology
(Elsevier, 2010)
The effect of acid activation on the textural properties of a bentonite from Serbia was investigated using response surface methodology. The influence of activation parameters (temperature, time, acid normality, solid-to-liquid ...
Co-aluminosilicate based electrodes
(Elsevier, 2010)
The influence of aluminosilicate support on the catalyst efficiency was investigated. Three different aluminosilicate materials containing cobalt (II) ion as active specie for phenol or nitrite oxidation were obtained. The ...
Organo-inorganic bentonite for simultaneous adsorption of Acid Orange 10 and lead ions
(Elsevier, 2010)
Partial substitution of the interlayer cations of a local bentonite (Bogovina) by hexadecyl trimethylammonium ions (HDTMA) was performed to prepare adsorbents able to simultaneously adsorb toxic metal cations and organic ...
