三聚磷酸根型锌镁铝三元类水滑石的合成

摘要

This experiment adopts the nucleation/crystallization segregation to prepare P3O10-5 Mg-A1,Zinc-A1 and Mg-Zinc-Al hydrotalcite,and discusses [Mg2 +]、[Al3 +]、[Zn2 +] metal cation of different concentrations have an influence on ternary hydrotalcite layer board structure.Through three kinds characterization methods of XRD,FT -IR and TG/DTA,thermal decomposition properties and layered structure of three kinds LDHs are analyzed.Results show that the experiment successfully synthesized three kinds water talc,which are Mg-Al-P3O10LDHs,ZincAl-P3O10LDHs and Zinc-Mg-Al-P3O10LDHs; As Mg content is fewer in the LDHs,thermal weightlessness temperature moves to low temperature area.%本实验采用成核/结晶隔离法制备了P3 O10-5根型Mg-A1,Zn-A1和Mg-Zn-Al类水滑石,探讨不同的浓度的[Mg2+]、[Al3+]、[Zn2+]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-Al-P3O10LDHs、Zn-Al-P3O10 LDHs和Zn-Mg-Al--P3O10 LDHs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.
