摘要
制备了第一过渡金属(Cr,Mn,Fe,Co,Ni,Cu,Zn)磷钨、磷钨钒两种杂多酸系列的13种杂多酸盐.对上述产物分别通过原子吸收和分光光度法进行元素分析,用FT-IR进行表征,确定了这些杂多酸盐的组成.实验表明磷钨、磷钨钒两个系列杂多酸盐都为1∶12系列的Keggin结构杂多化合物.研究了这些杂多酸盐在空气、氮气两种气氛下的TG-DTA,讨论了磷钨、磷钨钒两个系列杂多酸盐的热稳定性.
The first transition metal （Cr, Mn,Fe,Co, Ni,Cu,Zn） salts of tungstophosphoric acid and tungstovanadophosphoric acid were synthesized. The compounds were characterized by infrared spectroscopy （ IR ）, thermogravimetric -differential thermal analysis （TG - DTA ）, atomic absorption spectroscopy and spectrophotometry. The results showed that both tungstophosphoric salts and tungstovanadophosphoric salts are all the 1：12 series heteropoly compounds with Keggin structure. Their thermal stability at air and nitrogen atmosphere were studied with TG - DTA method.
