Voltammetric determination of fenbendazole in veterinarian formulations
(Elsevier B.V., 2002-09-05)
A versatile voltammetric method for quantitative determination of fenbendazole (FBZ) in commercial tablets has been proposed, where direct dissolution of tablets is carried out in 0.1 mol l(-1) tetrabutylamoniun tetrafluorborate ...
Electrochemical behavior and voltammetric determination of pyrazinamide using a poly-histidine modified electrode
(2013-01-21)
Pyrazinamide (Pyrazinecarboxamide-PZA) is a drug that is used to treatment tuberculosis. In the present work, the voltammetric behavior of PZA was studied using a screen-printed modified electrode (SPCE). The modified ...
Voltammetric sensor for amoxicillin determination in human urine using polyglutamic acid/glutaraldehyde film
(Elsevier B.V. Sa, 2008-08-12)
A voltammetric sensor for determination of amoxicillin (AMX) was developed based on a glutaraldehyde cross-linked polyglutamic acid modified glassy carbon electrode. The proposed method is based on pre-concentration of AMX ...
Electrochemical reduction and voltammetric determination of diloxanide furoate in non-aqueous medium
(2005-09-01)
The electrochemical reduction of diloxanide furoate (DF) in acetonitrile on glassy carbon electrode was studied in this work. It was observed that DF is reduced after a reversible one-electron transfer followed by an ...
Voltammetric determination of ethyl acetate in ethanol fuel using a Fe 3+/Nafion®-coated glassy carbon electrode
(2013-01-14)
A voltammetric method for the determination of ethyl acetate in ethanol fuel using a Fe3+/Nafion®-coated glassy carbon electrode (GCE) is proposed. The ethyl acetate present in the ethanol fuel was previously converted to ...
Electrochemical investigation of the voltammetric determination of hydrochlorothiazide using a nickel hydroxide modified nickel electrode
(Elsevier B. V., 2015-12-01)
The preparation and electrochemical characterization of a nickel hydroxide modified nickel electrode as well as its behavior as electrocatalyst toward the oxidation of hydrochlorothiazide (HCTZ) were investigated. The ...
Enhanced detection of ponceau 4r food dye by glassy carbon electrode modified with reduced graphene oxide
(2018-06-01)
This paper reports the development of a glassy carbon electrode modified with a reduced graphene oxide (r-GO/GCE) for the determination of the food dye named Ponceau 4R (PNC). The modified sensor presented excellent signal ...
Voltammetric determination of isoprenaline in pharmaceutical preparations using a copper(II) hexacyanoferrate(III) modified carbon paste electrode
(Elsevier B.V., 2004-09-01)
The electroanalytical determination of isoprenaline in pharmaceutical preparations of a homemade carbon paste electrode modified with copper(II) hexacyanoferrate(III) (CuHCF) was studied by cyclic voltammetry. Several ...
Voltammetric sensor for sodium nitroprusside determination in biological fluids using films of poly-L-lysine
(Wiley-Blackwell, 2007-05-01)
Sodium nitroprusside (NP), a commercial vasodilator, can be pre-concentrated on vitreous carbon electrode modified by films of 97.5%: 2.5% Poly-L-lysine (PLL): glutaraldehyde (GA). This coating gives acceptable anion ...
Determination of the relative contribution of phenolic antioxidants in orange juice by voltammetric methods
(Elsevier B.V., 2004-10-01)
The electrochemical oxidation of caffeic, chlorogenic, sinapic, ferulic and p-coumaric acids was investigated by cyclic voltammetry on acetate buffer pH 5.6 on glassy carbon electrode and modified glassy carbon electrode. ...
