Magnetically Responsive Calcium Carbonate

2019-12-12 · Here we report the fabrication of magnetically responsive calcium carbonate microcrystals produced by coprecipitation of calcium carbonate in the presence of citrate-stabilized iron oxide nanoparticles. We demonstrate that the calcite microcrystals obtained possess superparamagnetic properties due to incorporated magnetite nanoparticles and can be manipulated by an external magnetic

Quantitative analysis of calcium carbonate formation

2020-4-15 · This research studies the influence of static magnetic fields on the structure of calcium carbonate (CaCO 3) crystals.Experiments were conducted by exposing Ca 2+ and CO 3 2− solutions to magnetic fields. The solutions were then combined to form CaCO 3 particles. Three characteristics of CaCO 3 formation reaction have been investigated, namely absorbance differentiation, vibrational

Biogenic Calcium Carbonate with Hierarchical Organic

2021-3-13 · Calcium carbonate from geological sources (geo-CaCO3, e.g., calcite, aragonite) is used extensively in removing heavy metals from wastewater through replacement reaction. However, geo-CaCO3 has an intrinsically compact crystalline structure that results in low efficiency in pollutant removal and thus its use may produce enormous sludge. In this work, biogenic calcium carbonate (bio-CaCO3
