Electrode Mechanism Analysis by Linear Sweep Voltammetry. II. Application of Derivative Cyclic Voltammetry.

Determination of Mexiletine in Pharmaceutical Preparations by Linear Sweep Voltammetry

A simple and rapid method for determination of mexiletine in pharmaceutical preparations was developed and validated using linear sweep voltammetry (LSV). The proposed method was based on electrochemical oxidation of mexiletine at platinum electrode in acetonitrile solution containing 0.1 M LiCIO4. The well-defined an oxidation peak was observed at +1.11 V. The calibration curve was linear for ...

Determination of Bosentan in Pharmaceutical Preparations by Linear Sweep, Square Wave and Differential Pulse Voltammetry Methods

In this study, simple, fast and reliable cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV) methods were developed and validated for determination of bosentan in pharmaceutical preparations.

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...
