A sensitive electrochemical sensor for rapid and selective determination of nitrite ion in water samples using modified carbon paste electrode with a newly synthesized cobalt(II)-Schiff base complex and magnetite nanospheres

Application of N,N’‐Bis(acetylacetonato)propylenediimine Copper(II) Complex as Mediator for Glucose Biosensor

“…For example, some authors used Schiff base complexes as a part of plasticized membranes for Cu(II) selective sensors and as a part of polymeric membrane with Cd(II) Schiff base complexes for determination of iodide . Carbon paste electrode based on Co(II) Schiff base complex and magnetite nanospheres were used as sensor for determination of nitrite ion in water . Also, Ru(III) Schiff base complex was used as a part of electrochemical sensor for determination of L‐cysteine and Ru(II) thiolato complex was used as a self assembled monolayer on Au electrode, in which, horseradish peroxidase was potentiostatically incorporated and the resultant biosensor was used for the amperometric determination of H 2 O 2…”

“…[30] Carbon paste electrode based on Co(II) Schiff base complex and magnetite nanospheres were used as sensor for determination of nitrite ion in water. [31] Also, Ru(III) Schiff base complex was used as a part of electrochemical sensor for determination of L-cysteine [32] and Ru(II) thiolato complex was used as a self assembled monolayer on Au electrode, in which, horseradish peroxidase was potentiostatically incorporated and the resultant biosensor was used for the amperometric determination of H 2 O 2 . [33] In this paper, we describe a simple construction of a glucose biosensor.…”

Determination of nitrite in tap water: A comparative study between cerium, titanium and selenium dioxide doped reduced graphene oxide modified glassy carbon electrodes

“…Nitrites have found wide application in various industries. In food production nitrites are usually used as food preservative (E250) and in others fields of industry nitrites are used for inhibition of corrosion processes in big water industrial units [1][2][3][4]. These salts are present in the soil, sometimes in high quantity, which can cause their presence in high level in natural waters [3].…”

“…These salts are present in the soil, sometimes in high quantity, which can cause their presence in high level in natural waters [3]. The potential metabolites of nitrite could be N-nitroso compounds, which possess carcinogenic effect [4][5][6]. Nitrites also can cause different health implications such as gastric and nasopharyngeal problems when people are seriously exposed [7][8][9].…”

“…Due to these facts a development of a fast, simple, cost-effective, selective and sensitive method for its quantification is very important. Numerous methods have been reported in the literature dealing with nitrites quantification, such as spectrophotometric methods [10,11], flow methods [12], chemiluminescence [13] as well as electroanalytical methods [4,[14][15][16][17][18][19][20][21][22].…”
