摘　　要：研究了水杨酸酯与硝酸稀土之间的配位还原反应。用紫外、红外、循环伏安等方法对配位还原反应进行了验证。红外结果表明水杨酸酯与硝酸稀土进行了配位;紫外、循环伏安等结果都表明在水杨酸酯稀土配合物的作用下,硝酸根被还原成了亚硝酸根进而成了亚硝基化产物,配合物起到了类似硝酸还原酶的功能。配合物化学式含有Ln(NO3)(H2O)(NO-MS)结构单元,Ln为La,Y等稀土,MS为水杨酸甲酯。Coordinated reduction between salicylate and rare earth nitrate was studied and confirmed by UV-vis, IR and CV （ cyclic voltammetry）. The results of IR indicated that the salicylate was coordinated with rare earth nitrate. UV-vis and CV proved that nitrate was reduced to nitrite and nitrosation products by the coordination. All the results showed that the complex of salicylate and rare earth can act as nitrate reductase. The chemical formula of the complex has the structure of Ln （NO3） （H20） （NO-MS）, in which Ln is rare earth, such us Y and La. MS is methyl salicylate.
