在碳纳米管修饰的玻碳电极(GCE)上构建了一种高灵敏度的氧化石墨烯伏安传感器，用于橙皮素的灵敏检测。系统研究了橙皮素在该传感器上的电化学行为，提出了一种新的测定橙皮素的伏安法。详细讨论了橙皮素的氧化还原特性，并提出了合理的反应机理。作为分析方法，响应电流与橙皮素浓度在5.0×10−8~3.0×10−6mol.L−1之间呈线性关系，检出限为2.0×10−8mol.L−1(S/N=3)。方法用于生物样品和中草药百合花中橙皮苷的检测，结果令人满意。
A highly sensitive voltammetric sensor, based on reduced graphene oxide on SWCNTs modified glassy carbon electrode (GCE), was constructed and used for sensitive detection of hesperetin. The electrochemical behavior of hesperetin at this sensor was investigated systematically and a novel voltammetric method for determination of hesperetin was proposed. The redox characters of hesperetin was discussed in detail and a reasonable reaction mechanism was proposed also. As the analytical method, the response currents were linear relationship with the hesperetin concentrations in the range of 5.0×10−8to 3.0×10−6mol L−1, with a detection limit of 2.0×10−8mol L−1(S/N=3). The method was also applied successfully to detect hesperetin in biological samples and Chinese herbal medicine Flos buddlejae with satisfactory results.
