基于rGO@ZIF-8异质结构材料的金丝桃苷电化学传感器的构建与性能
Construction and performance of hyperoside electrochemical sensor based on rGO@ZIF-8 heterostructured material
通过原位合成的方法制备了rGO@ZIF-8异质结构材料,并用于构建高灵敏的金丝桃苷电化学传感器。基于ZIF-8及rGO两者的协同效应,显著提高了电极比表面积及电子传输效率。利用循环伏安及差分脉冲伏安法深入研究了金丝桃苷在该传感器上的电化学行为,最优条件下,响应峰电流与金丝桃苷在0.001~2.0、2.0~80 μmol/L范围内呈良好的线性关系,检出限(S/N=3)为0.5 nmol/L,将该方法成功应用于中药饮片中金丝桃苷的检测,与高效液相色谱法测定结果高度吻合,为中药饮片的质控分析提供了方法。
In this study,the rGO@ZIF-8 heterostructured material was prepared by in-situ synthesis and used to construct a highly sensitive electrochemical sensor for hyperoside.Due to the synergistic effect of ZIF-8 and rGO,the specific surface area and the electron transfer efficiency of the electrode were significantly improved.The electrochemical behavior of hyperoside on this sensor was examined in depth by cyclic voltammetry and differential pulse voltammetry.Under the optimal conditions,the response peak current showed an excellent linear relationship with the concentration of hyperoside in the ranges of 0.001-2.0 μmol/L and 2.0-80 μmol/L.The detection limit (S/N=3) was 0.5 nmol/L.This method was successfully applied to the determination of hyperoside in TCM,and the results were highly consistent with those determined by HPLC,providing a technical means for the quality control analysis of traditional Chinese medicine.
