Determination of trace sulfite by direct and indirect methods using differential pulse polarography

Determination of trace nitrite by direct and indirect methods using differential pulse polarography and application

“…This result is expected since as can be seen from polarograms the sulfite peak used is sharper and larger than the nitrite peak. According to our former studies [21] there will be only interference from cadmium, because of the peak overlap with sulfite. However, this interference could be eliminated by the addition of EDTA, cadmium peak shifted to more negative potential because of complex formation.…”

Survey of sulfites in wine and various Turkish food and food products intended for export, 2007–2010

“…Although there have been recent proposals for new approaches to determining sulfites, for example such as the use of differential pulse polarography (Yilmaz and Somer 2007) and piezoelectric detectors (Palenzuela et al 2005), methods for Official purposes have been in use for more than 80 years and are still widely used. These methods, such as the Monier-Williams distillation procedure (Monier-Williams 1927) or variations thereof, are time-consuming but have proved to be robust.…”

Rapidly responsive and highly selective fluorescent probe for sulfite detection in real samples and living cells

“…Despite these advantages, sulfites are toxic, and consuming even low levels of sulfite can cause diseases to some people, such as allergic reaction, skin allergy, asthma, and gastrointestinal diseases [1]. The United States Food and Drug Administration required labeling of products that contain more than 10 µg/mL of sulfite [2][3][4].…”
