摘　　要：以钴镍盐为前驱体,采用溶胶-凝胶法在碳纤维(CF)上原位制备了钴镍纳米材料Co-Ni/CF,采用电化学方法研究了邻苯二酚在Co-Ni/CF电板上的电化学性能。结果表明,Co-Ni/CF电板对邻苯二酚具有良好的电催化特性,邻苯二酚浓度在1~3 mmol·L^(-1)范围内与还原峰电流呈良好的线性关系,相关系数为0.99239,检出限为1.9×10^(-8)mol·L^(-1),该方法具有灵敏度高、线性范围宽、稳定性好等特点,可用于邻苯二酚含量的测定。Using cobalt salt and nickel salt as precursors, Co-Ni/carbon fiber nanomaterials were prepared in-situ by sol-gel method. The electrochemical properties of catechol on Co-Ni/CF electrode were studied. Re- suits showed that Co-Ni/CF electrode had excellent electrocatalytie characteristics to catechol,and the peak cur- rent increased linearly with, the concentration of catechol in the range of 1~3 mmol· L^-1 （R2 =0. 99239） with a detection limit of 1. 9 ×10^-8mol·L^-1. The method had good sensitivity, stability and reproducibility, with a broad linear range,and could be used for determination of catecho] content.
