Formation of Basic Magnesium Carbonate from Magnesium Chloride and Sodium Carbonate in Aqueous Solution

Synthesis of Needle-like Aragonite from Calcium Chloride and Sparingly Dissoluble Magnesium Carbonate

Needle-like o r b ranch-like a ragonite was prepared from sparingly dissoluble magnesium carbonate and calcium chloride aqueous solution. The morphology, particle size, and aspect ratio of the product were characterized with SEM. The polymorphs and crystal size were characterized with XRD. Comparing with calcium sulfate and sodium carbonate that were used in our previous study, a high reactant ...

A basic magnesium carbonate, a possible dimorph of artinite, from Unst, Shetland

Efflorescent outgrowths and compact vein-like material from brucite-rich specimens is a basic magnesium carbonate and possibly a dimorph of artinite. X-ray, infrared, chemical and thermal data reveal the material to be different from known ffatural basic magnesium carbonates.

The Kinetics of Binding Carbon Dioxide in Magnesium Carbonate

Magnesium isotope fractionation during hydrous magnesium carbonate precipitation with and without cyanobacteria

The hydrous magnesium carbonates, nesquehonite (MgCO3 3H2O) and dypingite (Mg5(CO3)4(OH)2 5(H2O)), were precipitated at 25 C in batch reactors from aqueous solutions containing 0.05 M NaHCO3 and 0.025 M MgCl2 and in the presence and absence of live photosynthesizing Gloeocapsa sp. cyanobacteria. Experiments were performed under a variety of conditions; the reactive fluid/bacteria/mineral suspen...

The color removal of dye wastewater by magnesium chloride/red mud (MRM) from aqueous solution.

In this study, the MgCl2/red mud system (MRM) was used to investigate the color removal efficiency of dye solutions. Parameters such as the effect of the dosage of red mud (RM) and MgCl2 have been studied. The effect of pH on the conversion rate of Mg2+ has also been studied. The color removal efficiency of MRM was compared with that of PAC/RM and PAC/NaOH. Meanwhile, the color removal efficien...
