A boron-doped diamond electrode (BDDE) was applied for a simple, and sensitive electroanalytical determination of a fungicide, bromacil (Bro), using differential-pulse voltammetry (DPV). For the first time, the electrochemical oxidation of Bro using a BDDE at +1.65 V vs. an Ag/AgCl reference electrode in Britton-Robinson (BR) buffer, pH 2.0 was investigated. To obtain the optimum experimental conditions, the effects of the pH, modulation amplitude, modulation time and step potential were studied. Under optimum conditions, the DP voltammetric determination of Bro was performed in the concentration range of 5.00 x 10(-6)-7.50 x 10(-5) mol L-1 (LOD = 1.26 x 10(-6) mol L-1, LOQ = 4.22 x 10(-6) mol L-1), and the validation of the method was carried out. The developed procedure was successfully applied to determine Bro in a spiked river water sample by the standard addition method. To achieve valuable information regarding the electrochemical oxidation mechanism of the pesticide Bro on BDDE, the cyclic voltammetry (CV) technique was applied. Additionally, the influence of Bro on the corrosion properties of stainless steel employed to produce agricultural tools was investigated by means of electrochemical methods, e.g. linear polarization close to the corrosion potential for corrosion rate determination, and potentiodynamic anodic polarization to characterize the resistance to pitting corrosion. Corrosion damage was characterized by means of optical microscopy. (C) 2016 Elsevier B.V. All rights reserved.
