Determination of hydroquinone in a square wave voltammetry procedure using a graphite-polyurethane composite electrode
In order to a better characterization of a graphite-polyurethane composite intended to be used as a voltammetric sensor, the performance in a square wave voltammetric procedure was investigated. Using hydroquinone (HQ) as a probe, the electrode showed to be useful in square wave voltammetry with limit of detection of 0.28 μmol L-1, with recoveries between 99.1 and 101.5%. The results of the pro...
متن کاملDetermination of clopidogrel using square wave voltammetry
The determination of clopidogrel, an antiplatelet agent, was performed at a gold electrode in pH 3.7 acetate buffer using cyclic voltammetry (CV) and square wave voltammetry (SWV). Each voltammogram was characterized by the well defined peak at approximately 1.0 V. The current of anodic stripping peak exhibited a linear dependence on the clopidogrel concentration in the range from 317.89 to 935...
متن کاملDetermination of Riboflavin by Nanocomposite Modified Carbon Paste Electrode in Biological Fluids Using Fast Fourier Transform Square Wave Voltammetry
Herein, fast Fourier transformation square-wave voltammetry (FFT-SWV) as a novel electrochemical determination technique was used to investigate the electrochemical behavior and determination of Riboflavin at the surface of a nanocomposite modified carbon paste electrode. The carbon paste electrode was modified by nanocomposite containing Samarium oxide (Sm2O3)/reduced gra...
متن کاملDetermination of Paracetamol at a Graphite-Polyurethane Composite Electrode as an Amperometric Flow Detector
Um eletrodo compósito de grafite-poliuretana sem modificação foi avaliado como um detector amperométrico para análise em fluxo, na determinação de paracetamol (APAP) em formulações farmacêuticas. Uma curva analítica foi obtida com região linear entre 5,00 x 10 e 5,00 x 10mol L, com um limite de detecção de 18,9 mol L e 180 determinações por hora, depois de parâmetros otimizados como potencial d...
متن کاملDetermination of Quercetin in a Pharmaceutical Sample by Square-Wave Voltammetry Using a Poly(vinylpyrrolidone)-Modified Carbon-Paste Electrode
Um eletrodo de pasta de carbono modificado com o polímero poli(vinilpirrolidona) foi avaliado para o estudo eletroquímico e a determinação eletroanalítica da quercetina. Sobre este eletrodo, voltamogramas cíclicos da quercetina apresentaram três picos de oxidação localizados em +0,32, +0,78 e +1,04 V. A eletro-oxidação no primeiro pico conduz à formação da orto-quinona correspondente, a qual po...
