摘要:

采用液相沉淀法, 以硝酸铋[Bi(NO3)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(NO3)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, Bi3+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.

Key words: Calcium carbonate, In situ preparation, Precipitation reaction, Conch-like morphology
