Determination of Analgesics (Dipyrone and Acetaminophen) in Pharmaceutical Preparations by Cyclic Voltammetry at a Copper(II) Hexacyanoferrate(III) Modified Carbon Paste Electrode
(Bentham Science Publ Ltd, 2009-10-01)
Copper(II) hexacyanoferrate(III) (CuHCF) modified carbon paste electrode was used for the electroanalytical determination of dipyrone and acetaminophen in pharmaceutical preparations by cyclic voltammetry. Several parameters ...
Electrochemical reduction and cathodic stripping voltammetric determination of clotrimazole
(Sociedade Brasileira de Química, 2001-04-01)
Clotrimazol é reduzido em eletrodo de mercúrio em tampão fosfato pH > 6 através de um processo reversível de um elétron. O processo eletródico apresenta forte efeito de adsorção, o qual pode ser minimizado na presença de ...
Regeneration of poly-L-lysine modified carbon electrodes in the accumulation and cathodic stripping voltammetric determination of the cromoglycate anion
(Elsevier B.V., 2003-07-27)
Cromoglycate is accumulated on a poly-L-lysine (PLL) modified carbon electrode best from pH 4 solution, where it is anionic and the PLL is cationic, and at which pH the cromoglycate gives a good reduction peak at -0.82 V. ...
Indirect polarographic and cathodic stripping voltammetric determination of cefaclor as an alkaline degradation product
(Elsevier B.V., 1999-11-01)
Cefaclor is not reducible at a mercury electrode, but it can be determined polarographically and by cathodic stripping voltammetry as its initial alkaline degradation product which is obtained in high yield by hydrolysis ...
A cubic silsesquioxane modified with purpald®: Preparation, characterization and a voltammetric application for determination of sulfite
(2013-06-01)
A novel composite formed by interaction of a octa(3-chloropropyl)octasilsesquioxane modified with Purpald®, and its subsequent reaction with silver and hexacyanoferrate (III) (AgHSP), was synthesized and initially characterized ...
Simultaneous voltammetric determination of carbendazim and carbaryl in medicinal plant infusions with a boron-doped diamond electrode
(Taylor & Francis Ltd, 2017)
This study is aimed to develop an electroanalytical methodology using a boron-doped diamond electrode to determine simultaneously and selectively carbendazim (CBZ) and carbaryl (CAR). In previous studies using cyclic ...
Voltammetric Studies of Cobalt Hexacyanoferrate Formed on the Titanium (IV) Phosphate Surface and its Application to the Determination of Sulfite
(Electrochemical Science Group, 2012-03-01)
Titanium (IV) Phosphate (TiPh) composite was prepared using a easily methodology of the synthesis. As a second step, TiPh was reacted with Cobalte (TiPhCo) and subsequent hexacyanoferrate was added (TiPhCoHCF). A preliminary ...
Voltammetric determination of 17 alpha-ethinylestradiol hormone in supply dam using BDD electrode
(Springer, 2016)
In this work, a simple method for electroanalytical determination of 17 alpha-ethinylestradiol (EE2) hormone in natural waters was developed using a boron-doped diamond electrode (BDD). The analyses were performed using ...
Simultaneous determination of zinc, copper, lead, and cadmium in fuel ethanol by anodic stripping voltammetry using a glassy carbon-mercury-film electrode
(Springer, 2004-09-01)
A new, versatile, and simple method for quantitative analysis of zinc, copper, lead, and cadmium in fuel ethanol by anodic stripping voltammetry is described. These metals can be quantified by direct dissolution of fuel ...
