Simultaneous voltammetric determination of nitrate and nitrite ions using a copper electrode pretreated by dissolution/redeposition.
Nitrate and nitrite ions were found to be successfully electroreduced at an in situ electrochemically pretreated copper electrode in acidic media, and their reduction peaks of a cyclic voltammogram were found at two distinct electrode potentials. Cyclic voltammetric experiments revealed a highly sensitive behavior of the pretreated copper electrode upon the electroreduction of nitrate and nitri...
متن کاملNitrite reduction by copper complexes.
A series of copper complexes have been synthesised as potential agents for the catalytic reduction of nitrite anions. The ligands and corresponding copper complexes have been characterised by using a range of techniques including X-ray crystallography, NMR, microanalysis, mass spectrometry, infra-red spectroscopy, electrochemical studies and density functional theory calculations. For complexes...
متن کاملElectrochemical determination of nitrite using silver nanoparticles modified electrode.
In this work, we report the fabrication and characterization of silver nanoelectrode ensembles (Ag-NEEs) on a glassy carbon electrode. For this purpose, Ag nanoparticles (NPs) were anchored to the mercaptopropyl functionalized MCM-41 type silica spheres utilizing the chemisorption property of Ag NPs by -SH groups. The successful anchoring of Ag NPs into the silica matrix is characterized by sev...
متن کاملDetermination of Nitrate in Sea Water by Cadmium-copper Reduction to Nitrite*
An accurate, dependable determination of 0-60 ,ug-at./l. of NOs -N in sea water has been developed. The sample is treated with tetrasodium ethylenediaminetetraacetate solution and passed through a column of copperized cadmium filings. A nearly quantitative reduction of nitrate to nitrite results. Nitrite is then determined by a diazotization method. Neither sulphide nor high nitrite concentrati...
متن کاملMorphology, Microstructure and Electrocatalytic Properties of Activated Copper Surfaces
The deliberate manipulation of electrodic surfaces consists of an area of continuing interest, because this approach leads to an improvement in the ability to recognize molecules and carry out electron transfer processes at higher rates. Hence, one of the dominant subjects in electrochemistry is the attempt to control the chemical composition and morphological structure of the electrode surface...
