Electrochemical detection of various contaminants has been widely used as a powerful tool in quality
control of food and analysis of environmental samples. In this work, electrochemical procedures for
determination of pesticides imidacloprid, metribuzin and metamitron are presented. Thin film layer
electrode is used as a working electrode, while chronopotentiometry is applied as an electroanalytical
technique. For all analysed pesticides, several solution conditions and instrumental parameters
influencing the electroanalytical response of the analytes are examined and optimised in respect to the
height of the analytical signals. The obtained analytical signals for the investigated pesticides are the
result of irreversible reduction of the analyte on the working electrode surface, and for each analyte
one reduction wave is obtained. Under the optimal experimental conditions, proposed
chronopotentiometric methods are validated with the respect to linearity, limit of detection, l...imit of
quantification, precision, selectivity, recovery and accuracy. Validated chronopotentiometric methods
are applied for analysis of selected pesticides in spiked tap and river water samples. In the analysis of
real samples, proposed methods showed to be sensitive and reproducible, fast (1-5 s analysis time),
and simple since no complicated sample preparation is needed, and therefore are suitable for routine
analysis of pesticides in water samples.
