钨砷系列杂多蓝的研究Ⅱ——1∶11钨砷双系列稀土杂多蓝

Studies on Tungstoarsenate Heteropoly Blues Complexes Ⅱ ——Studies on Tungstoarsenate Heteropaly of Double-Series with Rare Earth

利用控制电位电解的方法合成了４种未见文献报道的杂多蓝，Ｋ１１Ｈ２〔Ｌｎ（ＡｓＷ１１Ｏ３９）２〕·ｘＨ２Ｏ（Ｌｎ＝Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ），并利用等离子体原子发射光谱等对其进行了元素组成的分析，利用ＩＲ、ＵＶ、极谱、光电子能谱、电子顺磁共振、热重差热等测试手段，对其结构和性质进行了研究．

The four new tungstoarsenate heteropoly blues with rare earth,K 11 H 2 Ln(AsW 11 O 39 ) 2 · X H 2O(Ln=La,Ce,Pr,Nd),were prepared by controlling potential electrolysis. The element was analysed by equil-ion and atomic emission spectrometry. The structure and properties were studied by using IR,UV,spectra polarograply.SPS, ESR and thermal analyses
