DETERMINATION OF ULTRA-TRACE AMOUNTS OF COBALT BY ADSORPTIVE DIFFERENTIAL PULSE VOLTAMMETRY USING ACDA (2-AMINOCYCLOPENTENE- 1-DITHIOCARBOXYLIC ACID)
The present work describes a selective, rapid and sensitive method for the determination of cobalt using the adsorptive differential pulse voltammetry technique. The method is based on the accumulation of Co(II) complex with 2-aminocyclopentene-1-dithiocarboxylic acid on a hanging mercury drop electrode, followed by measurement of the current of the adsorbed complex. The effects of experimental...
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 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...
