Abstract

The simultaneous electrochemical determination of two insecticides thiaclopride and imidaclopride by an electrode, modified by a squaraine dye – VO(OH) hybrid composite, has been evaluated from the mathematical point of view. The correspondent model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It was shown that the squaraine dye – VO(OH) composite may be an efficient electrode modifier for thiaclopride and imidaclopride determination, despite of the hybridity of the reduction mechanism in the last case. On the other hand, the oscillatory behavior for this system will be caused only by DEL influences of the electrochemical stage.
