Textural properties of synthetic nano-calcite produced by hydrothermal carbonation of calcium hydroxide
German Montes-Hernandez, Alejandro Fernandez-Martinez, L. Charlet +2
The hydrothermal carbonation of calcium hydroxide (Ca(OH)2) at high pressure of CO2 (initial PCO2 1/4 55 bar) and moderate to high temperature (30 and 90 1C) was used to synthesize…
Arsenite sorption and co-precipitation with calcite
Gabriela Roman-Ross, Gabriel Cuello, Xavier Turrillas +2
Sorption of As(III) by calcite was investigated as a function of As(III) concentration, time and pH. The sorption isotherm, i.e. the log As(III) vs. log [As(OH)3 degrees / Assat] p…
Rhombohedral calcite precipitation from CO2-H2O-Ca(OH)2 slurry under supercritical and gas CO2 media
German Montes-Hernandez, François Renard, Nicolas Geoffroy +2
The formation of solid calcium carbonate (CaCO3) from aqueous solutions or slurries containing calcium and carbon dioxide (CO2) is a complex process of considerable importance in t…
Arsenic uptake by gypsum and calcite: Modeling and probing by neutron and x-ray scattering
Alejandro Fernandez-Martinez, Gabriel J. Cuello, Gabriela Roman-Ross +4
Here we report on two structural studies performed on As-doped gypsum (CaSO4 2H2O) and calcite (CaCO3), using neutron (D20-ILL) and x-ray (ID11-ESRF) diffraction data and EXAFS (BM…
