The electrochemical properties of dinotefuran (DNF) were studied by SW voltammetry over the pH range 2.08.0 using a silver amalgam film electrode Hg(Ag)FE. The mechanism of electroreduction was analyzed. The dependence of the peak current on pH, buffer concentration, the nature of the buffer, amplitude, frequency, step potential and scan rate were investigated. The repeatability, precision and recovery of the developed method were checked. The detection and quantification limits were found to be 2.01x10-7 and 6.71x10-7 mol?L-1, respectively. The standard addition method was used to determine DNF in spiked carrot juice.
