| 摘 要： | 采用液相沉淀法,以硝酸铋Bi(NO_3)_3]为添加剂来调控碳酸钙晶体的形状与大小,制备了海螺状碳酸钙粒子.通过扫描电子显微镜(SEM)、X射线衍射仪(XRD)、热重分析仪(TGA)、原子荧光光谱仪(AFS)等对产物的结构和性能进行了表征.结果表明,在60℃条件下,添加20 mL浓度为2 g/L的Bi(NO_3)_3溶液可得到海螺状球霰石型碳酸钙粒子,且其荧光性明显增强.在碳酸钙的成核过程中,Bi~(3+)的加入起到了显著的调控作用.

| Abstract: | Using liquid phase precipitation method, special conch-like calcium carbonate particles were prepared with bismuth nitrate as an additive at 60 ℃. The structure and performance of the resulting calcium carbonate were characterized by means of scanning electron microscopy( SEM), X-ray diffraction( XRD), thermogravimetric analysis(TGA) and atomic fluorescence spectroscopy( AFS). The results showed that the fluorescence of the conch-like calcium carbonate particles was enhanced obviously. Bi3+ played a significant controlling role in the nucleation process of calcium carbonate. |
