摘要:

以L-组氨酸和十二烷基苯磺酸钠(SDBS)作为CaCO3生长调节剂,用粉末X射线衍射、红外光谱测试技术对生成的CaCO3晶体进行了表征,扫描电子显微镜对生成的CaCO3晶体形貌进行了分析,研究了表面活性剂浓度、温度和溶剂的组成对CaCO3晶型和形状的影响。 结果表明,在实验条件下表面活性剂的浓度对CaCO3晶型没有影响,但影响晶体的形状,温度和溶剂的组成对CaCO3晶型和晶体形状有很大的影响。

Abstract:

The crystal growth of CaCO3 with dodecylbenzenesulfonate sodium(SDBS) and L-histidine as growth regulators were studied were characterized with powder X-ray diffraction and infrared spectrometry. We also used scanning electron microscopy to analyze the crystal shapes of generated CaCO3 in order to study the effect of surfactant concentration, temperature and solvent composition on the crystal morphology and shape of CaCO3. The results show that under experimental conditions, the concentration of surfactant SDBS has no effect on the crystal morphology of CaCO3, but affect the shapes of the crystals, in the mean time, the temperature and solvent composition greatly affect the crystal morphology and crystal shape of CaCO3.

Key words: L-histidine, DMF, SDBS, calcite, Aragonite, vaterite
