Square Wave Voltammetry (SWV) is a potentiostatic method that offers some advantages to common techniques like Cyclic Voltammetry (CV), in that the waveform is a series of pulses increasing along a linear baseline, where current is measured in a forward pulse and reverse pulse. However, the reversible nature of CV means that it is easy to determine if the electrochemical signal generated corresponds to a simple redox process, or a more complicated coupled reaction (Armstrong et al., 2018; Bard & Faulkner, 2001; Compton & Banks, 2011). This therefore minimize the contribution of the capacitive current generated in the case of CV and therefore increase the sensitivity of the pulse method. DPV and SWV are preferred when sensitivity wants to be improved. The inverse of the cycle length is the frequency, 1/. Square-Wave Voltammetry The excitation signal consists of a symmetrical square- wave pulse of amplitude E superimposed on a staircase waveform of step height E, where the forward pulse of the square wave coincides with the staircase step.

Draw the excitation signal, the response signal and the concentration profile for DPV and SWV. It was shown that the current response remarkably increased after GCE electrode was coated with f-MWCNTs and the current intensity of the oxidation/reduction peaks increased 64% in comparison to the GCE electrode. Square Wave Voltammetry (SWV) is a large-amplitude differential technique in which a wave form composed of a symmetrical square wave, superimposed on a base staircase potential, is applied to the working electrode (Osteryoung & Osteryoung, 1985). In this study, MIPs were used as synthetic recognition elements toward dodecyl gallate as they were generated by molecular imprinting of the target analyte in the presence of a functional monomer (o-phenylene diamine) solution. Electrochemical sensors based on nanomaterials for the determination of food polyphenols by square wave voltammetry.
