Rapid quantification of sodium dithionite by ion chromatography / Travis James in Industrial & engineering chemistry research, Vol. 51 N° 22 (Juin 2012)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 22 (Juin 2012) . - pp. 7742-7746 Titre : Rapid quantification of sodium dithionite by ion chromatography Type de document : texte imprimé Auteurs : Travis James, Auteur ; Allen Apblett, Auteur ; Nicholas F. Materer, Auteur Année de publication : 2012 Article en page(s) : pp. 7742-7746 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Ion chromatography Résumé : Sodium dithionite is an oxidizable sulfur oxyanion often employed as a reducing agent in environmental and synthetic chemistry. This industrially important reagent slowly decomposes into a variety of sulfur oxyanions. Thus, a rapid method to assess purity of a given sample is crucial. Despite the importance of this material to the wood pulping and textile industries, a rapid, reliable method to quantify dithionite remains a challenge. Current methodologies require extensive bench-top chemistry. Ion chromatography can provide a simple one-step method that can easily be automated to rapidly and accurately determine the concentration of dithionite. The results are in excellent agreement with those obtained using a multistep iodometric titration.
