Abstract

The sucralose electrochemical determination, assisted by a polymer of a novel acridinic derivative, doped by a novel quinolinicaminoacid, has been theoretically evaluated. The sucralose is capable to interact either with the monomer, or with the dopant, changing the double electric layer (DEL) capacitance and film conductivity. These changes may be responsible for electrochemical instabilities. Nevertheless, the analysis of the model by linear stability theory and bifurcation confirms that this polymer may be applied as an efficient electrode modifier in the sucralose determination in neutral media, being applied for sucralose determination in biological liquids and beverages. The electrochemical response has to be clear and easy to interpret..
