15 صفحه اولDetermination 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. The proposed methods were based on electrochemical oxidation of bosentan at platinum electrode in acetonitrile solution containin...

متن کاملTheory of linear sweep voltammetry with diffuse charge: Unsupported electrolytes, thin films, and leaky membranes.
Linear sweep and cyclic voltammetry techniques are important tools for electrochemists and have a variety of applications in engineering. Voltammetry has classically been treated with the Randles-Sevcik equation, which assumes an electroneutral supported electrolyte. In this paper, we provide a comprehensive mathematical theory of voltammetry in electrochemical cells with unsupported electrolyt...
متن کاملDetermination 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 ...
