通过化学共沉淀法制备了CuO-NiO复合氧化物。在最优条件下,该复合物修饰玻碳电极对葡萄糖检测的线性范围为2×10-6~4.1×10-3mol/L;灵敏度为4116μA·L·mmol-1·cm-2;检测限为0.2μmol/L(S/N=3)。传感器可用于葡萄糖检测。
CuO-NiO composite oxide was prepared by chemical coprecipitation method. Under the optimal conditions, the linear range of the complex-modified glassy carbon electrode for glucose detection was 2 × 10-6 ~ 4.1 × 10-3mol / L, the sensitivity was 4116μA · L · mmol-1 · cm-2, and the limit of detection Was 0.2 μmol / L (S / N = 3). The sensor can be used for glucose detection.
