A sensitive SWV method based on BPPGE and EPPGE was developed to determine the concentration of MAN in spiked samples, showing linear responses over specified concentration ranges. The method was successful in determining MAN with good recovery rates, and CV was used to understand the electrode process mechanism of MAN.
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 mu mol L-1 and 0.5 to 10.0 mu mol 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.
