“…Many studies have been conducted to explore simple, convenient, and costeffective methods to produce nanoparticles from various range of biomaterials for various industrial purposes [1][2][3][4][5][6][7][8][9]. One of the leading biomaterials which has been intensely investigated is the inorganic calcium carbonate (CaCO 3 ) material.…”

“…Each of these polymorphisms possesses different properties which determine their special characteristics [5]. In fact, numerous studies on both the physical and chemical properties of calcium carbonate polymorphisms have been accomplished since several decades ago [2,3,5,[12][13][14][15][16][17][18][19].…”

“…From the fabrication of micron-sized calcium carbonate particles in the early days up to the synthesis of desirable nanosized particles today, many studies have used the bottom-up approach via the precipitation process, either through carbonation [3,5,6,11,18] or through solution [12-14, 17, 19, 24, 25, 27] route for the production of inorganic calcium carbonate raw material over the past few years. However, the new trend of employing nature-based materials such as mineral products [3,5,6] and mineralized organisms [1, 2, 7-10, 20-22, 26] to derive calcium carbonate biomaterial has been highly preferable in terms of environmental preservation and efficient use of mineralized seashell byproducts due to its abundance in nature, which can provide raw material source at reasonably low cost and also present good purity of mineral components naturally.…”

The development of cockle shell-based calcium carbonate aragonite polymorph nanoparticle synthesis method using the technique of mechanical stirring in the presence of dodecyl dimethyl betaine (BS-12) incorporated with surface functionalization demonstrated high homogeneity of sample product with good nanoparticles dispersion. The cockle shell-based calcium carbonate aragonite nanoparticle with functionalized surface was characterized using transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), particle size distribution, pH measurement analysis, Fourier Transform Infrared (FTIR) spectroscopy, and X-ray diffraction (XRD). Surface functionalization was proven to improve the overall size and shape of the nanoparticles and enhance their dispersion properties, preventing coarse agglomeration among nanoparticles in general. The improved method was verified to retain its aragonite crystalline nature. Additionally, surface functionalization did not increase the size of nanoparticles throughout the modification process. This facile preparation using naturally occurring cockle shells as the main source is environmentally friendly because it provides relatively low cost of raw material source as it is abundantly available in nature and has good mineral purity content. Hence, high quality production of surface functionalized cockle shell-based calcium carbonate aragonite polymorph nanoparticles can potentially be exploited and produced on a large scale for various industrial applications, especially for biomedical purposes in the near future.

CO2 Mineralization Using Brine Discharged from a Seawater Desalination Plant

et al. 2017

CO 2 mineralization is a method of sequestering CO 2 in the form of carbonated minerals. Brine discharged from seawater desalination is a potential source of Mg and Ca, which can precipitate CO 2 as forms of their carbonate minerals. The concentration of Mg and Ca in brine are twice those in the seawater influent to desalination process. This study used a cycle for CO 2 mineralization that involves an increase in the pH of the brine, followed by CO 2 bubbling, and, finally, filtration. To the best of our knowledge, this is the first time that non-synthesized brine from a seawater desalination plant has been used for CO 2 mineralization. The resulting precipitates were CaCO 3 (calcite), Mg 5 (CO 3 ) 4 (OH) 2 ·4H 2 O (hydromagnesite), and NaCl (halite) with these materials being identified by X-ray Diffraction (XRD), Fourier transform infrared (FTIR) and thermo gravimetric-differentail thermal Analysis (TGA)-DTA. Despite the presence of Ca with Mg in brine being unfavorable for the precipitation of Mg carbonate, Mg reacted with CO 2 to form hydromagnesite at a yield of 86%. Most of the Ca formed calcite, at 99% yield. This study empirically demonstrates that brine from seawater desalination plants can be used for CO 2 mineralization.
