钼钒磷杂多酸铵蓝的合成和性质研究

STUDIES ON THE SYNTHESES AND PROPERTIES OF AMMONIUM MOLYBDOVANADOPHOSPHATE BLUE

本实验采用分步加原料的方法，以不同的磷钼钒比，直接合成了三种１：１２系列的钼钒磷杂多酸铵蓝，即（ＮＨ４）４Ｈ２·１５Ｈ２Ｏ（ｂｌｕｃ—１），（ＮＨ４）５Ｈ２·和（ＮＨ４）６Ｈ２·３０Ｈ２Ｏ（ｂｌｕｃ－３），并研究了反应条件对这些钼钒磷杂多酸铵蓝形成的影响．通过元素分析、电位滴定、电子光谱和Ｘ射线衍射等测试手段研究了配合物的性质，并确定了配合物的组成．

hree specimens of ammonium molybdovanadophosphate bule have heen synthesized by a method of stepwise adding raw material in the different molar ratio of P:Mo:V.The effect of reaction condition on the formation of these ammonium molybdovanadophosphate bule has been studied. New hctcropoly blue with formulas:(Nc4)4H2·15H2O,(NH4)5H2·20H2O,(NH4)6H2·30H2O were studied by clemental analysis,potcntionlctric titration, electronic spectra and X-ray powder diffraction.
