Trace Determination of Carbendazim Fungicide Using Adsorptive Stripping Voltammetry with a Carbon Paste Electrode Containing Tricresyl Phosphate
Popis výsledku v původním jazyce
In this study, a carbon paste electrode based on tricresyl phosphate (TCP-CPE) as a binder has been applied to the voltammetric characterization and determination of Carbendazim fungicide (methyl-1H-benzimidazol-2-yl-carbamate, MBC). The pH effect (in Britton-Robinson buffers, pH 2.0-8.0), as well as the presence of 2-hydroxypropyl-?-cyclodextrin (HPCD) on the electrochemical behavior of MBC were investigated. In the potential range of interest, the oxidation signal was observed with the overall shape strongly dependent upon pH and exhibiting the most favorable signal-to-noise ratio in mild acidic solutions (pH 4.0). This has indicated that also protons are involved in the electrode transformation of MBC. Furthermore, it was confirmed that addition of3.6?10-5 mol L-1 HPCD significantly enhanced the sensitivity towards the target analyte. The experimental conditions optimised for the determination of MBC in the differential pulse adsorptive stripping voltammetric mode (DPAdSV) were as
