Theoretical Description for Lugduname and Perillartin Electrochemical Determination by Cathodic Route

In this work, the possibility of lugduname and perillartin electrochemical determination by cathodic process has been given. Both substances are reduced, forming the amino group, which may become protonated in an acidic medium, affecting the DEL ionic force and thereby affecting the analytical signal interpretation. Although even in the acidic medium, the system is electroanalytical efficient, it is recommended to use the neutral or mildly acidic medium for the electroanalytical process. This permits us to use the electrochemical sensor to monitor the sweetener concentration in most soft beverages.
