| 摘 要： | 采用本室创制的返混沉淀法制备了酒石酸插层水滑石(LDHs),采用X射线衍射(XRD)、红外光谱 (FT.IR)电感耦合等离子光谱 (ICP)对其结构和层板组成进行表征。考察了层间距与制备条件 pH值的关系,发现插层产物层间距随pH值增加存在先增加后减小的变化趋势,这是由于酒石酸离子在层间的排列发生变化造成的。

| Abstract: | Tartaric acid intercalated layer double hydroxide(LDHs) was prepared by a new method created at our laboratory, and characterized by XRD, FT IR and ICP. The relationship between the interlayer distance and pH condition of the preparation was investigated. It is found that the interlayer distance increases first and then decreases with increase in pH value, which is due to the change of orientation of tartaric anions in the interlayer region. |
