三聚磷酸根型锌镁铝三元类水滑石的合成

本实验采用成核／结晶隔离法制备了P3O10^-5根型Mg-Al，zn-A1和Mg-Zn-A1类水滑石，探讨不同的浓度的Mg^2＋]、Al^3＋]、Zn^2＋]金属阳离子对三元水滑石层板结构的影响，利用XRD，FT-IR和TG／DTA三种表征手段，对三种LDHs的热分解性质及层状结构进行分析。结果表明：实验成功合成了Mg-A1-P3010LDHs、Zn-A1-P3010LDHs和Zn-Mg-Al--P3010LDHs三种类水滑石；随着LDHs中Mg含量减少，热失重温度向低温区移动。

Synthesis of Zn-Mg-Al Hydrotalcite-like Compounds and Characterization

This experiment adopts the nucleation/crystallization segregation to prepare P3O10^-5 Mg-A1, Zinc-A1 and Mg-Zinc-A1 hydrotalcite, and discusses Mg^2＋], A1^3＋ ], Zn^2＋ ] metal cation of different concentrations have an influence on ternary hydrotalcite layer board structure. Through three kinds characterization methods of XRD, NF -IR and TG/DTA, thermal decomposition properties and layered structure of three kinds LDHs are analyzed. Re- sults show that the experiment successfully synthesized three kinds water tale ,which are Mg-A1-P3O10LDHs, Zinc- A1-P3O10LDHs and Zinc-Mg-A1-P3Ol0LDHs; As Mg content is fewer in the LDHs, thermal weightlessness tempera- ture moves to low temperature area.
