摘要: 采用水溶液合成法制备了具有Keggin型结构的十一镍锆钼杂多酸盐Na6·20H2O(NiZrMo),并对其进行表征及分析.元素分析表明,镍锆钼之间的物质的量之比满足1:1:11的关系;热重/差热分析说明合成的杂多酸盐具有比较好的热稳定性并带有20个结晶水;红外光谱、X射线衍射及紫外光谱表征充分表明合成的杂多酸盐其阴离子仍保持Keggin型结构;扫描电镜分析表明,具有比较好的大分子化合物的基本特征和比较规则的晶体结构.以NiZrMo杂多酸盐为催化剂降解酸性绿B(AGB)染料废水,降解率最高可达95.72%.

Abstract: The heteropoly salt, Na6�20H2O(NiZrMo)with Keggin structure of the 1:1:11series, was synthesized by the aqueous solution method, and characterized and analyzed. The elemental analysis showed that the molar ratio of Ni,Zr and Mo was accord with 1:1:11. The thermogravimetric analysis/differential thermal analysis(TG/DTA) indicated that the NiZrMo had good thermostability and it contained twenty molecules of crystallization water. The characterization by Fourier transform infrared spectroscopy(IR),X-ray powder diffraction analysis(XRD) and the ultraviolet spectrum(UV) showed that the anionic of the NiZrMo heteropoly salt possessed Keggin structure. The analysis of scanning electron microscopy(SEM) showed that it had the basic feature of the macromolecular compound and a regular crystal. The NiZrMo heteropoly salt was used as the catalyst to degrade the acidid-green B(AGB) dyeing wastewater enhanced by the ultrasonic, and the degradation rate could reached 95.72%.
