In this study, simple, fast and reliable cyclic voltammetry, linear sweep voltammetry, square wave voltammetry and differential pulse voltammetry methods were developed and validated for determination of etodolac in pharmaceutical preparations. The proposed methods were based on electrochemical oxidation of etodolac at platinum electrode in acetonitrile solution containing 0.1 M lithium perchlo...

In this paper we obtain the analytical solution for the reverse Werential pulse O P ) technique for a slow electronic transfer process, starting fkom expressions obtained previously for the faradaic response to a triple potential pulse. The solutions are valid for the planar approximations of a static mercury drop electrode and of a dropping mercury electrode. An irreversible reduction process ...

The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...

In this study, 2-aminobenzoic acid (ABA) has been used as complexing ligand for simultaneousdetermination of metal ions by adsorptive cathodic stripping voltammetry (AdCSV), for the firsttime. Thus, a selective and sensitive procedure was presented for simultaneous determination oflead, cadmium and nickel using ABA and differential pulse-adsorptive cathodic strippingvolt...

The modified glassy carbon electrode (GCE) was prepared with 6-amino-4-(3,4-dihydroxyphenyl)-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile (pyrazole derivative (AMPC)) and functionalized multi-walled carbon nanotubes. In this research, electrocatalytic activity of nanocomposite (AMPC/MWCNTs) has been studied by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoa...

In this study a new method of preconcentration, separation and efficient measuring of so-called hollow fiber solid / liquid phase microextraction has been introduced for the determination of trace amounts of lorazepam (LRZ) in water samples, urine and hair using differential pulse voltammetry. To this end, a hybrid adsorbent material was used that involved ionic liquid assisted magnetic multi-w...

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...
