Adsorptive Stripping Voltammetry in Lipophilic Vitamins Determination
The aim of this contribution was to check if adsorptive stripping differential pulse voltammetry (AdSDPV) is suitable tool for sensitive simultenous electrochemical detection of lipophilic vitamins. Retinol (vitamin A1), cholecalciferol (vitamin D3), α-tocopherol (vitamin E) and phylloquinone (vitamin K1) were selected as representatives. All electrochemical measurements were performed in two s...
متن کاملDetermination of vanillin in commercial food product by adsorptive stripping voltammetry using a boron-doped diamond electrode.
A method for the determination of food additive vanillin was developed by adsorptive stripping voltammetry. Its determination was carried out at the anodically pre-treated boron-doped diamond electrode in aqueous solutions. Using square-wave stripping mode, the compound yielded a well-defined voltammetric response in phosphate buffer, pH 2.5 at +1.14 V (vs. Ag/AgCl) (a pre-concentration step be...
متن کاملDetermination of trace procaine hydrochloride by differential pulse adsorptive stripping voltammetry with a Nafion modified glassy carbon electrode.
A sensitive and selective method for the determination of procaine hydrochloride with a Nafion-modified glassy carbon electrode has been developed. The voltammetric behavior of procaine hydrochloride on the Nafion-modified electrode indicated that the modified electrode not only increased the sensitivity of the determination of procaine hydrochloride, but also catalyzed the electrode process. P...
متن کاملDetermination of trace levels of diosmin in a pharmaceutical preparation by adsorptive stripping voltammetry at a glassy carbon electrode.
A systematic study on the electrochemical behavior of diosmin in Britton-Robinson buffer (pH 2.0-10.0) at a glassy carbon electrode (GCE) was made. The oxidation process of the drug was found to be quasi-reversible with an adsorption-controlled step. The adsorption stripping response was evaluated with respect to various experimental conditions, such as the pH of the supporting electrolyte, the...
متن کاملDetermination of Fenitrothion in Commercial Formulations by Square Wave Voltammetry and UV-Vis Spectroscopy
A voltametria de onda quadrada foi utilizada com o eletrodo de gota suspensa de mercúrio para determinar o conteúdo de Fenitrothin em três diferentes formulações comerciais. Em princípio, as determinações de Fenitrothion foram feitas em uma solução tampão BR (pH 10,5) preparada com água pura. Nestas soluções, os limites de determinação e quantificação encontrados foram 5,20x10 μmol L (1,44 ppb)...
