采用电解法合成了Keggin结构稀土钼磷二、四电子杂多蓝，通式为和。通过元素分析、紫外可见光谱、光电子能谱、(31)P核磁共振谱等方法对产物进行了表征，对12种化合物进行了防治番茄花叶病毒的研究，发现其中部分化合物能有效阻止番茄花叶病毒对番茄的感染，治疗效果达70％－95％。关键词：##4稀土;;杂多蓝;;番茄花叶病毒
Electrolytic synthesis of Keggin structure rare earth molybdenum phosphorus two, four electronic heteropoly blue, and the general formula. The products were characterized by elemental analysis, UV-visible spectrum, photoelectron spectroscopy and (31) P nuclear magnetic resonance spectroscopy. The study on 12 compounds against tomato mosaic virus found that some of them could effectively prevent tomato flower Leaf virus on tomato infection, the treatment effect of 70% -95%. Keywords: ## 4 rare earth; heteropoly blue; tomato mosaic virus
