Electrochemical sensor for sulfite determination based on a nanostructured copper-salen film modified electrode
(Electrochimica Acta, 2009-07-30) [Artigo]
The electrochemical preparation described herein involved the electrocatalytic oxidation of sulfite on a platinum electrode modified with nanostructured copper salen (salen=N,N'-ethylenebis(salicylideneiminato)) polymer ...
Determination of Analgesics (Dipyrone and Acetaminophen) in Pharmaceutical Preparations by Cyclic Voltammetry at a Copper(II) Hexacyanoferrate(III) Modified Carbon Paste Electrode
(Current Analytical Chemistry, 2009-10-01) [Artigo]
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 ...
Determination of the chemical oxygen demand (COD) using a copper electrode: a clean alternative method
(Journal of Solid State Electrochemistry, 2009-05-01) [Artigo]
A clean alternative method for the determination of chemical oxygen demand (COD) was developed using a copper electrode as an electrocatalytic sensor. The measuring principle is based on oxidation current of organic compounds ...
Development of an electrochemical sensor for potassium ions based on KSr(2)Nb(5)O(15) modified electrode
(Proceedings of The Eurosensors XXIII Conference, 2009-01-01) [Artigo]
In the work described by this paper, we studied the development of a selective potassium ion sensor constituted of a carbon paste electrode modified (CPEM) with a novel KSr(2)Nb(2)O(15). The material KSr(2)Nb(2)O(15) is ...
