Simple and rapid voltammetric method for simultaneous determination of all‐trans‐retinyl acetate (RAc) or all‐trans‐retinyl palmitate (RPa) and α‐tocopheryl acetate (α‐TOAc) has been proposed. The respective method was based on the anodic oxidation of the compounds of interest by square‐wave voltammetry in acetone with 0.1 mol L−1 LiClO4 at the glassy carbon electrode. The procedure was also beneficial with respect to simple dissolution of sample directly in the supporting electrolyte. The all‐trans‐retinyl acetate could be quantified in two linear ranges (3.1–140 μmol L−1 and 140–400 μmol L−1) and α‐tocopheryl acetate in linear range 5.3–400 μmol L−1 with detection limits of 0.9 μmol L−1 RAc (or 0.8 μmol L−1 RPa) and of 1.6 μmol L−1 α‐TOAc. Selected commercial cosmetic products were analysed achieving satisfactory recoveries.

“…In a study, researchers developed a DPV technique by which retinol could be detected in modified carbon paste electrode with 30% (w/w) SDS (CPE/SDS) (Žabčíková, Mikysek, et al, 2018). The findings indicated that the electrode surface repelled the organic solvent in the presence of surfactants.…”

Voltammetric sensors are simple, powerful, and cheap equipment with easy principles, which have been widely used in electrochemical studies to investigate the properties of the electroactive species. Surfactants are frequently used in the construction of voltammetric sensors to enhance the sensitivity and selectivity of the sensor, which significantly impacted the electrode function in terms of dissolving organic compounds, creating a specific orientation of molecules on the surface of the electrodes, and enhancing electron transfer reactions. This review focuses on the recent contributions of surfactants in the development of efficient voltammetric sensors. In addition, other ingredients commonly employed alongside surfactants, such as nanomaterials, conducting polymers, and composite materials, have been discussed. The comprehension of these aspects can guide the expansion and the use of surfactants in the electrochemical sensing scope.

“…The Pt:Co/IL/CPE showed LOD of 0.04 μM and the authors also analysed the electrode utility using cabbage and tablet specimens [21]. S. Žabčíková et al [22] used CV to investigate the oxidation mechanism of all-trans retinol and their esters in non-aqueous, aqueous organic mixture, and pure aqueous media. Their most sensitive oxidation peak appearing at +0.8 V vs. Ag/AgCl was used for the development of a new direct voltammetric method based on DPV for the determination of retinol at carbon paste.…”

This review article examines some advancements in electrochemical sensors for vitamin detection in the past few decades. Vitamins are micronutrients found in natural foods essential for maintaining good health. Most vitamins cannot be synthesized by a body and must be obtained externally from natural food. Vitamins make a class of organic chemicals that shortage can cause various ailments and diseases, and consumption can become harmful if it exceeds the usually needed level. Because of these factors, vitamin detection has become highly significant and sparked interest over the past few decades. The electrochemical sensors function on the concept of electrochemical activity of practically all vitamins. This implies that concentrations of vitamins in the electrolyte may be detected by measuring the amounts of current generated at certain potentials by their oxidation and reduction at the working electrode surface. Voltammetric methods are superior to other methods because they are cheaper and show sharp sensitivity with faster analysis speed. The carbon-based electrodes, in particular carbon paste electrodes (CPE), have significant advantages like easier catalyst incorporation, surface renewability, and expanded potential windows with lower ohmic resistance. This review goes into detail about several electrochemical sensors involving CPE as the working electrode and its utilization to detect water- and fat-soluble vitamins.
