Long-range vs. short-range ordering in synthetic Cr-substituted goethites

Autor: Elsa E. Sileo, Graciela E. Magaz, Aline Y Ramos, Miguel A. Blesa

Publikováno v: Geochimica et Cosmochimica Acta. 68:3053-3063

A series of Cr-substituted goethites with (Cr:Fe molar ratio up to 0.12) were prepared. Thermal analysis of the solids indicates the formation of cation-deficient compounds that are more stable towards the transformation to hematite as the Cr content

Chromium oxides in sediments: comparison of surface characterization by electrophoretic mobilities and Fourier transform IR–attenuated total eflection measurements

Autor: Graciela E. Magaz, L. García. Rodenas, Miguel A. Blesa, Pedro J. Morando

Publikováno v: Surface and Colloid Science ISBN: 9783540212478

Adsorption of oxalate and chromate onto hydrous chromium(III) oxide and onto α-Cr2O3 was studied by spectroscopic methods (Fourier transform IR) and by measurement of electrophoretic mobilities. The Fourier transform IR spectra demonstrate the forma

Effect of Light on the Electrokinetic Behavior of TiO(2) Particles in Contact with Cr(VI) Aqueous Solutions

Autor: Graciela E. Magaz, Miguel A. Blesa, Luis A. García Rodenas, Ariel D. Weisz

Publikováno v: Journal of colloid and interface science. 230(1)

The electrokinetic behavior of titanium dioxide particles (Degussa P25, mainly composed of anatase) put in contact with chromium(VI) aqueous solutions is highly sensitive to light exposure under normal laboratory conditions. In the dark, adsorption o

Electrokinetic Behaviour and Interaction with Oxalic Acid of Different Hydrous Chromium(III) Oxides

Autor: Graciela E. Magaz, Luis García Rodenas, Pedro J. Morando, Miguel A. Blesa

Publikováno v: Croatica Chemica Acta
Volume 71
Issue 4

Three samples of hydrous chromium(III) oxide have been prepared by different procedures, and their electrokinetic mobilities have been measured. In mineral media, isoelectric points were found to be 8.45 ±0.15. This value is shifted from the solutio
