Optimising Adsorptive Stripping Voltammetry: Strategies and Limitations

open access: yesChemElectroChem, Volume 8, Issue 12, Page 2343-2352, June 14, 2021., 2021
The adsorptions of fipronil at the studied carbon electrodes are identified to be no more than mono‐layer, which intrinsically limits the electroanalytical performances of the nano‐particle‐modified electrode using adsorptive stripping voltammetry despite the fact that significantly larger signals are detected.
