- Abstract
Introduction: For the first time, the possibility of anodic electroanalytical detection of ledol -- the main toxin in the nectars and honeys of some toxic flowers -- by the electrode, modified by the conductive polymer composite with cobalt oxyhydroxide is evaluated. Methodology: The electrooxidation of ledol will be realized via cyclopropane ring, followed by the oxidation of the secondary alcoholic group to ketone. Results and discussion: Analysis of the corresponding model using linear stability theory and bifurcation analysis confirms that cobalt oxyhydroxide in composite with conductive polymer can serve as an effective anode modifier for determining ledol in honeys, nectars and other sources natural. As ledol is poorly ionized, the oscillatory behavior will only be caused by the effects of the electrochemical stage in the double electric layer (DEL). Conclusions: Cobalt oxyhydroxide can be used for detection of ledol for safety verification of honeys.
