摘　　要：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;;The 2e, 4e molybdophosphoric heteropoly blues containing rare earth elements were prepared by electrolytic method. The formulas are LnH2 [ PMo Ma O ] 15HZO and LnH4[ PMo8W Mol 000]' 15HzO, in which Ln consists of La, Ce, Pr, Nd, Sin and Gd. These compounds were characterized by ICP. IR. UV' TG-DTA. XPS and 31 P NMR. Twelve compounds were studied on preventing tomato mosaic virus. The results show that some of thesecompounds have high disease resistance ability from tomato mosaic virus with cure rate 70% 95%.
