Electrochemical oxidation and voltammetric determination of the antimalaria drug primaquine
(Taylor & Francis Inc, 2005-01-01)
Primaquine, an antimalarial drug, presents a well-defined oxidation peak around +0.6V vs SCE at a glassy carbon electrode that can be used for its determination. Calibration graphs were obtained for primaquine in B-R buffer ...
Electrochemical behavior of a glassy-carbon electrode chemically modified with cadmium pentacyanonitrosylferrate in the presence of tetrahydrothiophene
(Elsevier B.V. Sa, 2011-12-01)
A glassy-carbon electrode was modified with cadmium pentacyanonitrosylferrate film using cyclic voltammetry. The voltammetry behavior of the cadmium pentacyanonitrosylferrate on the glassy-carbon electrode shows a redox ...
Electrochemical Behavior of a Glassy Carbon Electrode Chemically Modified with Nickel Pentacyanonitrosylferrate in Presence of Sulfur Compounds
(Wiley-Blackwell, 2011-06-01)
The glassy carbon electrode was modified with a nickel pentacyanonitrosylferrate film by electrodeposition of Ni and subsequent derivatization with NaPCNF. The film was characterized by XPS and electrochemical methods. ...
Electrochemical reduction and cathodic stripping voltammetric determination of clotrimazole
(Soc Brasileira Quimica, 2001-01-01)
The reduction of clotrimazole at a mercury electrode, in phosphate buffer, pH>6, involves a reversible one-electron process. The electrochemical process presents a large contribution from adsorption effects. For the ...
Voltammetry of mercury (II) based on an organo-clay modified graphite electrode
(2008-11-17)
Organo-clay complex of ligand-hexadecyltrimethylammonium with montmorillonite was made for the purpose of application as a preconcentration agent in a chemically modified carbon paste electrode for determination of mercury ...
Determination of Mg (II) in biodiesel by adsorptive stripping voltammetry at a mercury film electrode in the presence of sodium thiopentone
(2013-01-01)
A mercury film electrode was used to determine Mg (II) in biodiesel by adsorptive stripping voltammetry in presence of sodium thiopentone. A linear response was obtained for Mg (II) in the concentration range of 6.0 × 10-7 ...
Determination of Glycerol in Biodiesel Using a Nickel(II) Oxyhydroxide Chemically Modified Electrode by Cyclic Voltammetry
(2013-07-01)
A glassy carbon electrode chemically modified with nickel oxyhydroxide from a nickel hexacyanoferrate (NiHCF) film was used to determine glycerol in biodiesel by cyclic voltammetry. The modified electrode exhibited a linear ...
Voltammetric determination of 4-nitrophenol at a lithium tetracyanoethylenide (LiTCNE) modified glassy carbon electrode
