Voltammetric characteristics of miconazole and its cathodic stripping voltammetric determination
(Academia Brasileira de Ciências, 2002-09-01)
Miconazol é reduzido no eletrodo de mercúrio em valor de pH acima de 6,0 envolvendo formação de composto organometálico, responsável por um comportamento polarográfico anômalo. O processo eletródico apresenta uma larga ...
Cathodic stripping voltammetric determination of cefaclor in pharmaceutical formulations
(Marcel Dekker Inc, 1999-01-01)
A sensitive method is described for the determination of cefaclor by cathodic stripping voltammetry at the hanging mercury drop electrode. cefaclor is accumulated at the electrode surface as a mercury salt, which is reduced ...
Voltammetric determination of persulfate anions using an electrode modified with a Prussian blue film
(Elsevier B.V., 2000-04-01)
Prussian blue [PB, iron(III) hexacyanoferrate(II)] films are effective for the electrocatalysis of the persulfate (peroxodisulfate)/sulfate redox system. This has been exploited in the voltammetric determination of persulfate ...
Development of an electrochemical sensor based on nanostructured hausmannite-type manganese oxide for detection of sodium ions
(2013-03-25)
The preparation and electrochemical characterization of hausmannite-type manganese oxide to use as a sensing material for sodium ion is described. This paper reports a new via synthetic to obtain of the hausmannite-type ...
Voltammetric determination of total iron in fuel ethanol using a 1,10 fenantroline/nafion carbon paste-modified electrode
(Electrochemical Science Group, 2008-03-01)
This work presents a methodology for iron determination in fuel ethanol using a modified carbon paste electrode with 1.10 fenantroline/nafion. The electrochemical parameters were optimized for the proposed system and the ...
Approach on the Electrochemical Reactivity of Poly-L-Glutamic Acid Against Doxorubicin and Its Application in the Development of a Voltammetric Sensor
(Electrochemical Science Group, 2010-10-01)
The poly-L-glutamic acid (PGA), was used a biodegradable polymers as conjugated to doxorubicin (DXR) and also in the modification glassy carbon electrode. The interaction operate via terminal amino groups of the drug and ...
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 ...
Anodic stripping voltammetric determination of aurothiomalate in urine using a screen-printed carbon electrode
(Wiley-Blackwell, 2006-08-01)
This work describes an electroanalytical method for determining gold(I) thiomalate, aurothiomalate, widely used for treatment of reumatoid arthiritis, using a screen-printed carbon electrode (SPCE). Aurothiomalate (AuTM) ...
