将C₆₀分散在ZnSe量子点溶液中，将此悬浮液滴涂于玻碳电极表面，自然晾干后制得ZnSe-C₆₀修饰电极，以循环伏安法研究了甲萘酚在此修饰电极上的电化学行为。结果表明：与ZnSe修饰电极和C₆₀修饰电极相比较，甲萘酚在ZnSe-C₆₀修饰电极表面的电化学响应效果最好。以pH 8.0磷酸盐缓冲溶液为底液，在1.0~-1.0 V电压范围内，以0.10 V·s^-1的扫描速率，采用微分脉冲伏安法对甲萘酚进行测定，甲萘酚的浓度在3.0×10^-6~1.5×10^-5mol·L^-1内与其氧化峰电流呈线性关系，检出限（3S/N）为1.0×10^-6mol·L^-1。方法应用于水样中甲萘酚的测定，结果与标准方法测定值相符，加标回收率在96.5%~104%之间，测定值的相对标准偏差（n=5）在2.3%~4.4%之间。

Fullerene (C₆₀) was dispersed in ZnSe quantum dot solution, and the obtained suspention was dropped on the surface of glass carbon electrode. After drying naturally, a ZnSe-C₆₀ modified electrode was obtained. The electrochemical behavior of α-naphthol at the modified electrode were investigated by cyclic voltammetry. As shown by the results, compared with ZnSe modified electrode and C₆₀ modified electrode, the best electrochemical response of α-naphthol on the surface of ZnSe-C₆₀ modified electrode was found. α-naphthol was determined by differential pulse voltammetry in the voltage range of 1.0——1.0 V, at a scan rate of 0.10 V·s^-1, using phosphate buffer solution (pH 8.0) as the base solution. Linear relationship was found between oxidation peak current with concentration of α-naphthol in the range of 3.0×10^-6-1.5×10^-5mol·L^-1, with detection limit (3S/N) of 1.0×10^-6mol·L^-1. The method was applied to the determination of α-naphthol in water samples, giving results in consistency with those obtained by the standard method. Values of recovery obtained by standard method were in the range of 96.5%-104%, and the relative standard deviations (n=5) of the measured values were in the range of 2.3%-4.4%.
