“…The N 2 H 4 is also an ideal fuel for the direct fuel cell system because its fuel electrooxidation process does not suffer from any poisoning effects [6][7][8][9]. Compounds containing SO 3 2-ions are used as preservatives in view of their antioxidant properties and as inhibitors of enzymatic and microbial activities in beverages, food, and pharmaceutical products [10]. The NO 2 -ion is a typical inorganic pollutant and its sources include wastes from fertilizer and preservative industries and adulterants in food [11][12][13][14].…”

Concurrent electrocatalysis and sensing of hydrazine, sulfite ions, and nitrite ions in a mixture were studied using electrodes modified by electrodeposited Au nanostructures (NSs). The β-cyclodextrin-mixed silicate sol-gel composite was dropcasted on the electrode surface and nucleation guided by β-cyclodextrin occurred, followed by the electrodeposition of Au NSs. The additive, β-cyclodextrin, played an evident role as a structure-directing agent; thus, small raspberry-like Au NSs were obtained. The modified electrodes were characterized by surface characterization techniques and electrochemical methods. The Au NSs-modified electrodes effciently electrocatalyzed the oxidation of toxic molecules such as hydrazine and sulfite and nitrite ions even in the absence of any other electron transfer mediator or enzyme immobilization. Wellresolved oxidation peaks along with decreased overpotentials were noticed during the electrooxidation process. The fabricated Au nanostructured electrode clearly distinguished the electrooxidation peaks of each of the three analytes from their mixture.

“…In recent years, many new methods have been reported, including electrochemistry (Chen et al, 2012;Isaac et al, 2006;Karimi-Maleh et al, 2012), ion chromatography (Koch et al, 2010;Zhong et al, 2012), liquid chromatography (Pizzoferrato, 1998;Theisen et al, 2010;S. Wang et al, 2007;Zuo and Chen, 2003), optical chemical sensors or biosensors (Alamo et al, 2010;Dinckaya et al, 2007;Filik and Çetintaş, 2012), flow injection (Navarrro et al, 2010;Ruiz-Capillas and Jiménez-Colmenero, 2009;Tzanavaras et al, 2009). Above-mentioned methods indeed greatly shorten the analysis time.…”

“…Despite these great advantages, the sulfite content in foods and beverages should be strictly limited due to its potential toxicity so that products containing more than the established threshold level must be adequately labeled [2]. Sulfite is also used in boilers and boiler-feed waters for dissolved oxygen control.…”

“…Meanwhile, there are several literature reports on chemically modified electrodes (CMEs) for sulfite sensing based on metal pentacyanonitrosylferrate [15,16], iron hexacyanoferrate film modified electrodes [24], polyaniline [27], poly[Ni-(protoporphyrin IX)] [28], [Ru(bpy)(tpy)Cl]PF6 [29], copper hydroxide [30] and sulfite oxidase biosensor based glassy carbon electrode coated with a thin mercury film [31]. The most important feature of such CMEs is perhaps the electrocatalysis of slow electron transfer reactions.…”

Electrocatalytic Oxidation and Determination of Sulfite with a Novel Copper‐Cobalt Hexacyanoferrate Modified Carbon Paste Electrode

The electrocatalytic oxidation of sulfite has been studied at a stable electroactive thin film of copper-cobalt hexacyanoferrate (CuCoHCF) hybrid electrodeposited on a carbon paste electrode (ECMCPE). A linear range of 5 mM to 5 mM of sulfite, with an experimental detection limit of 1 mM, was obtained using the cyclic voltammetric method. The oxidation of sulfite showed no significant fouling effect on the modified electrode surface at sulfite concentrations below 5 mM. The proposed modified electrode exhibited several attractive features, including simple preparation, fast response, good stability and repeatability, and could be applied to sulfite determination in real samples.
