“…According to these results, it is seen that the proton contribution in the reduction process is equal to the number of electrons. This result was found to be consistent with other studies in the literature [21][22][23][24][25]. Also, the evolution of Ep with pH shows two almost linear segments.…”

“…Using bare GCE [22] a low LOD value was obtained, but this value found is far from the analytical working range. Although the LOD value obtained with CP-BDDE [25] is close to the result obtained in our study, the cost of the method increases due to the electrode used. In addition to features such as environmentally friendly, cheap, easy to prepare and good analytical performance of the BiFE used as electrode in this study, the low LOD value obtained are important advantages.…”

“…In a similar study, the electrochemical properties of DESL in phosphate buffer (pH = 8.0) media were investigated using LSV technique on modified GCE [24]. Another research group stated in their study that it was oxidized at +1.55 V in phosphate buffer (pH = 4.0) media using the DPV technique on BDD electrode [25].…”

In this study, the electrochemical properties of desloratadine, which is in the second generation antihistamines group, were determined by bismuth film electrode (BiFE) in aqueous and aqueous/surfactant solutions. This compound gave an irreversible and diffusion-controlled reduction peak at about –1.65 V by cyclic voltammetry. It was found that the addition of cationic surfactants (cetyltrimethylammonium bromide (CTAB) increased the reduction current signal of desloratadine, while anionic (sodium dodecylsulfate (SDS) and nonionic (Tween 80) surfactants were found to have an adverse effect. Using linear sweep-cathodic stripping voltammetry, the analytical signal showed a linear correlation with a concentration of 0.1 to 4 µM in 0.04 M Britton–Robinson solution (pH = 8.0) in the presence of 5 mM CTAB, while the detection limit was calculated to be 11.70 nM (3.64 μgL –1 ). This method has been successfully applied for the quantitation of desloratadine in pharmaceutical and urine samples without the need for any separation.

“…Generally, the current is measured before and after the application of a pulse [33]. The difference between such two currents minimize the amount of capacitive current, leading to voltammograms with higher signal to noise ratios [98, 99]. A further feature of DPV is its higher resolution than those achievable by CV [33].…”

Electrochemical Methods to Evaluate the Antioxidant Activity and Capacity of Foods: A Review

et al. 2021

View full text Add to dashboard Cite

Antioxidants are an important class of food additives playing the fundamental role of retarding oxidation reactions in food. Although their functional role is well‐established, less clear is their mechanism of action. Electrochemical methods based on cyclic, differential pulse, square wave voltammetry and coulometry allow direct and rapid screening of antioxidant activity. Their main advantages are sensitivity, rapidity, simplicity and the capacity to directly measure the number of electrons transferred by an antioxidant offer advantage over conventional spectrophotometric assays. This review aims to summarize the most recent efforts towards the use of electrochemical methods to evaluate the antioxidant activity of foods.
