Abstract
The possibility of pyriproxyfen electrochemical detection in water (in neutral, or alkaline pH conditions) has been studied. During the analysis, piriproxyfen is transformed in a yet studied quinone-hydroquinonic system before the electrochemical reaction. By means of mathematical model development and analysis, using the linear stability theory and bifurcation analysis, the analytical efficiency conditions have been detected, including the optimal pH and potential range. The oscillatory and monotonic instability conditions have also been detected. These instabilities may be caused by double electric layer influences of the electrochemical reaction. The analysis may be driven in the presence of different organic, hybrid and inorganic modifiers. Nevertheless, the specific conditions for electrode modifying material stability are required for the electrochemical analysis of piriproxyfen
