| 摘 要： | 研究了水溶性聚乙二醇-6000(PEG-6000)、十二烷基硫酸钠(SDS)及PEG-6000/SDS复合物对CaCO3晶体形貌的调控作用;采用傅立叶变换红外光谱仪、扫描电子显微镜和X射线衍射仪分析了CaCO3微观形貌及晶体结构.研究表明,SDS和PEG-6000之间产生协同效应,有利于调控形成特定形貌的CaCO3晶体;利用这种复合体系制备CaCO3晶体,可以有效地模拟生物矿化过程中阳离子的摄取或富集.

| Abstract: | The influences of polyethylene glycol 6000 （PEG-6000）, sodium dodecyl sulfate （SDS） and PEG-6000/SDS composite on the crystallization and morphology of CaCO3 crystallites in aqueous solution were investigated. The molecular structure, micro-morphology, and crystal structure of as-prepared CaCO3 crystallites were analyzed by means of Fourier transform infrared spectrometry, scanning electron microscopy, and X-ray diffraction. It was found that SDS and PEG-6000 synergistically function in the reaction system thereby favoring to regulate the formation of CaCO3 erystallites with special morphology. Moreover, the present system adopted for synthesizing CaCO3 crystallites can well simulate the cationic intake or enrichment procedure during the biomineralization process. |
