A sensitive square‐wave voltammetry (SWV) method based on basal‐plane pyrolytic graphite electrode (BPPGE) and edge‐plane pyrolytic graphite electrode (EPPGE) was developed to determine the concentration of the pesticide mandipropamid (MAN) in spiked river water and grape juice samples. Under optimal experimental conditions, the SWV response of EPPGE and BPPGE was linear over the concentration ranges of 0.7 to 9.0 μmol L⁻¹ and 0.5 to 10.0 μmol L⁻¹, respectively. The method was successfully used to determine MAN in spiked samples with good recovery. Cyclic voltammetry (CV) was conducted to understand the mechanism underlying the electrode process of MAN.

边缘平面和基础平面热解石墨电极对杀真菌剂双歧ami灵敏测定的比较

建立了一种基于基平面热解石墨电极（BPPGE）和边缘平面热解石墨电极（EPPGE）的灵敏方波伏安法（SWV），用于测定加标的河水和葡萄中农药二丙酰胺（MAN）的浓度果汁样品。在最佳实验条件下，EPPGE和BPPGE的SWV响应分别在0.7至9.0μmolL ^-1和0.5至10.0μmolL ^-1的浓度范围内呈线性。该方法已成功用于测定加标样品中的MAN，回收率良好。进行循环伏安法（CV）以了解MAN电极过程的潜在机理。
