Novel Method for Determination of Trace Amounts of Citalopram in Tablets by Fast Fourier Continuous Cyclic Voltammetry at Au Microelectrode in Flowing Solutions

Neste trabalho, é apresentada a técnica voltamétrica cíclica contínua com transformada de Fourier rápida, para o monitoramento de quantidades ultra-traço de citaloprama em um sistema de injeção em fluxo. A forma de onda de potencial consiste em pulsos de potencial para limpeza e uma rampa de potencial foi continuamente aplicada a um microeletrodo (disco de ouro, com raio de 12,5 μm). O método d...

Application of adsorptive voltammetry for the detection of sub-nano molar cyclizine in biological fluids and tablets using fast Fourier transform continuous cyclic voltammetry in a flowing system.

An easy and fast Fourier transform continuous cyclic voltammetric technique (FFTCV) for monitoring of ultra trace amounts of cyclizine in a flow-injection system has been introduced in this work. The potential waveform, which was applied continuously on an Au disk microelectrode (12.5 microm in radius) consisted of the potential steps for cleaning, accumulation and potential ramp. The proposed ...

Selective and non-selective determination of heavy metal ions in flowing solutions by fast stripping cyclic voltammetry.

A simple and fast stripping voltammetric detection method has been designed for selective and non-selective measurements of heavy metal ions in a flow-injection system. A special computer numerical method is introduced for calculating the analyte signal and noise reduction, where the signal is calculated based on the partial and total charge exchange at electrode surface. For a selective determ...

Cyclic Voltammetry of Auranofin

The oxidative behavior of Auranofin, 2,3,4,6-tetra-O-acetyl-1-thio-beta-D-glucopyranosato- S(triethylphosphine)gold(I), was investigated by using cyclic voltammetry (CV) in 0.1 M Bu(4)NPF(6)/CH(2)Cl(2) and 0.1 M Bu(4)NPF(4)/CH(2)Cl(2) solutions using Pt working and auxiliary electrodes and a Ag/AgCI reference. CV studies at scan rates from 50-2,000 mV/s and Auranofin concentrations between 1 an...
