Determination of benzoate in cranberry and lingonberry by using a solid-contact benzoate-selective electrode

Published in Talanta, 2024

In this work, a solid-contact benzoate-selective electrode (benzoate-ISE) was developed by utilising poly(3,4-ethylenedioxythiophene) (PEDOT) as solid contact and a solvent polymeric membrane containing a 1,3-bis(carbazolyl)urea derivative as ionophore.
