本文采用一种现代流行的简易伏安传感器--石墨烯修饰电极(GR/GCE)，研究了氢化三氢呋喃的电化学性质。首次系统地研究了氢化三色酮的电极反应，并计算了一些动力学参数。并讨论了氢化三色酮在GR/GCE上的反应机理。基于GR/GCE对避孕酮的增敏作用，建立了一种灵敏的电分析方法，其线性范围为8×10−8~6×10−6moL L−1，检出限为4×10−8molL−1，经180次S积累后，用于实际样品中避孕酮的测定，结果令人满意。
In this paper, a modern popular simple voltammetric sensor, graphene modified electrode (GR/GCE), was employed for studying the electrochemical characters of hymecromone. The electrode reaction of hymecromone was investigated systematically for the first time and some kinetic parameters were calculated. The reaction mechanism of hymecromone at the GR/GCE was also discussed. Based on the enhancement sensing of the GR/GCE for hymecromone, a sensitive electroanalytical method was developed with a detection linear range of 8 × 10−8 to 6 × 10−6 mol L−1 and a detection limit of 4 × 10−8 mol L−1, which were obtained under accumulation for only 180 s. For proving the practical applicability of the proposed method, the determination of hymecromone in real samples was carried out with satisfactory results.
