摘要 以1,1′-双[2-(三乙氧基硅基)乙基]二茂铁(BTEF)和聚乙烯醇(PVA)为前驱物,采用溶胶-凝胶法制备了BTEF/PVA/玻碳修饰电极,优化了修饰电极的制备参数。结果表明,该修饰电极在0.1mol·L-1NaClO4磷酸盐缓冲溶液(pH=8.0)中呈现扩散和电子转移同时控制的可逆氧化还原过程,具有良好的稳定性。 A chemically modified glassy carbon electrode with 1, 1'-bis[2-(triethoxylsilyl)ethyl] ferrocene and poiy(vinylalcohol) as presursors was prepared via a sol-gel process. The preparation process of the modified electrode was optimized by cyclic voltammetry in 0. 1 mol · L^-1 NaC104 phosphate buffer (pH=8.0). The modified electrode exhibited a classical reversible cyclic voltammetry behavior with high stability.
