含水非晶碳酸钙的仿生矿化研究
Hydrous Amorphous Calcium Carbonate: A Biomimetic Mineralization Study
摘要
Abstract
A common route to form biogenic minerals during biomineralization is that the initial deposit of transient amorphous precursor phases and subsequent transformation into one of more stable crystalline phases. In terms of biogenic calcium carbonate minerals, amorphous precursor phase is generally considered to be formed under the joint regulation of biological macromolecules and inorganic ions. In this work, amorphous calcium carbonate (ACC) was synthesized in the presence of citrate anions by a biomimetic mineralization process. Structure and morphology of the synthesized ACC and the subsequently products from the ACC transformed were characterized using a wide range of techniques, including field emission scanning electron microscopy (FESEM),X-ray diffraction (XRD), Fourier infrared spectroscopy (IR) and thermal gravity analysis-differential thermal analysis (TG-DTA).The results showed that the multi-carbonate anions could induce the formation of ACC which had a similar composition to biogenic hydrous ACC. Therefore, our results suggest that some biomineralization-associated acidic biomacromolecules canalso induce the formation of biogenic ACC and transiently stabilize it.关键词
