摘 要: | 依据生物矿化的基本原理,以β-环糊精(β-CD)作为有机基质,采用仿生 的方法合成了具有独特形貌的文石型碳酸, 其中含有少量的β-环糊精。用X射线 粉末衍射(XRD)分析、扫描电子显微镜(SEM)、傅里叶变换红外吸收光谱(FT- IR)和电导率测定等手段对所得复合碳酸钙进行了表征,结果发现CaCO3结晶过程 中,β-环糊精与CaCO3之间存在着相互作用,并讨论了这种作用的可能机理。

Abstract: | Based on the basic principles of biomineralization, a novel aragonite (CaCo_3) with specific morphology was synthesized under the control of-cyclodextrin by the biomimetic method. In our experiments, the β-cyclodextrin were used as the organic matrix. The obtained composite CaCO_3 with small amount of β-cyclodextrin were characterized by X-ray powder diffraction (XRD) analysis and scanning electronic microscopy (SEM). Furthermore, according to the results of Fourier transform infrared spectroscopy (FT-IR) and measurement of conductance ratios, the possible mechanism of the interaction between β-cyclodextrin and CaCO_3 during the CaCO_3 formation process was discussed. |
