摘　　要：利用稀土镧配合物修饰的钨硅酸盐修饰玻碳电极,在酸性缓冲溶液中实现对生物小分子多巴胺的检测。实验结果表明镧配合物修饰的十二钨硅酸阴离子对生物小分子多巴胺的线性检测范围为0.2~6.5 mmol·L^(-1),而最低检测限(LOD)则为92.8μmol·L^(-1),明显低于裸玻碳电极的140μmol·L^(-1)。为开发新型多金属氧酸盐修饰电极的开发奠定了基础。The modified glassy carbon electrode modified by lanthanide complexes was used to detect the small molecule dopamine in acidic solution. The experimental results showed that the linear range of detection for dopamine is 0.2 -6.5 mmol ·L^-1 by lanthanum complex modified tungstosilicate. The minimum detection limit （LOD） is 92.8 mmol ·L^-1, which was lower than that of the bare glassy carbon electrode of 140 mmol ·L^-1. This work lays a foundation for the development of new polyoxometalate modified electrode.
