【摘要】 用离子交换法制备了三种迄今未见报导的钨铈杂多酸溶液。其阴离子组成分别为[CeW₈O₂₈]^4-、[CeW₁₀O₃₅]^6-和[CeW₁₂WO₄₂]^8-。其中12-钨铈杂多酸制得了稳定的固体,从而揭示了钨饰杂多化合物中一个新的系列——Ce-12W系列。对该固体酸进行了元素分析、红外光谱、电位滴定、X光衍射和差热、热重分析,并对其结构进行了初步探讨。更多还原

【Abstract】 We have for the first time prepared solutions of 3 stable cerium-tungsten heteropoly acids. Their anionic constitutions are CeW8O284-, CeW10O356-, and CeW12O428-. Preparation conditions of these heteropoly acids have been studied.Solid 12-tungstoceric acid has been isolated by the use of ion exchange-acidification method and examined with infrared spectrography, X-ray diffraction and differential thermal analysis.更多还原
