| 摘 要： | 将K2CO3和TiO2通过高温固相反应制得K2Ti4O9,经酸化处理后得到H2Ti4O9,用正十二胺乙醇溶液与之反应,获得正十二胺柱撑的层状化合物,采用X射线衍射(XRD)、红外光谱(IR)等方法对所得材料进行结构表征,并初步研究了有机胺支撑前后钛酸材料的吸附性能,实验结果表明:在钛酸钾材料的层间引入正十二胺有机基团后,层间距加大,吸附能力大大提高。

| Abstract: | The solid-phase reaction between K_2CO_3 and TiO_2 was used to prepare the precursor K_2Ti_4O_9.H_2Ti_4O_9 and them was further prepared by HCL solution.The organic titanate acid was obtained by the intercalation of n-dodecylamine.The structure of the resulting materials was confirmed by X-ray diffraction(XRD) and IR spectroscopy.The primary study of the adsorption capacity on the titanate acid and the organic titanate acid was conducted.Results showed that the resulting organic amine intercalated layered hybrid compounds had a larger interlayer space and a marked higer adsorption capacity compared to their precursor. |
