Sequential Determination of Benserazide and Levodopa by Voltammetric Method using Chloranil as a Mediator

Descrevemos um método eletroquímico para a determinação voltamétrica seqüencial de benserazida e levodopa usando cloroanil (CA) como eletro-catalisador. Para investigar a adequação do CA como mediador na oxidação eletrocatalitica da benserazida e levodopa, em solução aquosa, foram usadas a voltametria cíclica, voltametria de pulso diferencial, cronoamperometria e espectroscopia de impedância el...

Voltammetric Determination of Cysteine (2-amino-3-mercaptopropanoic acid, CySH) by Means of 4 4'-biphenol as a Homogeneous Mediator

In the present research, 4, 4'-biphenol was used as a homogeneous mediator for determining cysteine (CySH) on a Glassy Carbon Electrode (GCE). To describe the electrochemical properties of 4,4'-biphenol and to examine its electrocatalytic impacts on cysteine oxidation, both Cyclic Voltammetry (CV) and Linear Sweep Voltammetry (LSV) were employed. Our findings revealed that 4,4'-biphenol could s...

Design and Optimization of a New Voltammetric Method for Determination of Isoniazid by Using PEDOT Modified Gold Electrode in Pharmaceuticals

Isoniazid (INH) was studied with regard to its electrochemical treatment on a strongly alkaline solution of a poly (3,4-ethylenedioxythiophene)-modified gold electrode, using both cyclic voltammetry and controlled potential techniques. This composite electrode exhibited 4-fold higher oxidation of INH, in accordance with peak densities, than the bare gold electrode. It was used the central compo...
