摘要
本文介绍了两种杂多酸Na8[PMo7V5O4 0 ]、Na5[PMo10 V2 O4 0 ]的一般性质 ,以及它们的合成及表征。研究中通过等离子体发射光谱 (ICP -AES)分析和红外光谱、X射线衍射光谱进行表征 。
The general characters of heteropolyacids are introduced.The synthesis and characterization of two of them Na 8[PMo 7V 5O 40 ](HPA-5)and Na 5[PMo 10 V 2O 40 ](HPA-2) are discussed.The ICP-AES spectrum,FTIR spectrum and X-Ray Difraction were used in the studies on prepared heteropolyacids.It is deduced that their structures are analogous to the Keggin structure and the molecular formula are similar to the theoretic Na 8[PMo 7V 5O 40 ] and Na 5[PMo 10 V 2O 40 ].
