Chemiluminescence Determination of Sulfur Dioxide in Air Using Tris(1,10-Phenanthroline)Ruthenium−KIO₄System

Analytical applications of flow injection with chemiluminescence detection—a review

“…Four FI-CL applications have been reported for the determination of micromolar to sub-nanomolar levels of sulphur dioxide in air and sulphite in aqueous solution. Three of these methods used triethanolamine for initial adsorption, followed by CL reactions involving either ruthenium (2,2'-bipyridyl) 3 /potassium persulphate (125), Tris(1,10-phenanthroline) ruthenium-potassium periodate (126) or ruthenium (2,2'-bipyridyl) 3 -potassium permanganate (127). The fourth method was based on luminol CL, with luminol initially immobilized on an anion exchange column, then eluted by hydrolysis (124).…”

Periodate oxidation and its contribution to instrumental methods of micro-analysis—A review

“…The SO 2 -potassium periodate reaction system in acidic medium in the presence of the complex Ru(1,10-phenanthroline) 3 2+ was used for the determination of SO 2 in air [158].…”

On‐line chemical generation of tris(2,2′‐bipyridyl)ruthenium(III) and its application in CE with chemiluminescence detection

“…The chemical oxidation means, using conventional oxidants including lead dioxide [21,22], cerium(IV) [23,24], potassium permanganate [25,26], potassium periodate [27,28], and potassium bromate [29], has been a rapid and simple method to produce Ru(bipy) 3 31 effectively. Despite more than amine-containing analytes [21,30,31], organic acids [22][23][24][25]32] and sulfur-containing analytes [26][27][28][29]33] can be detected, the chemical generation method is still limited for the probable instability of the active Ru(bipy) 3 31 .…”

“…Despite more than amine-containing analytes [21,30,31], organic acids [22][23][24][25]32] and sulfur-containing analytes [26][27][28][29]33] can be detected, the chemical generation method is still limited for the probable instability of the active Ru(bipy) 3 31 . By far, only a few reports about CE-CL based on chemical generation of Ru(bipy) 3 31 have been published [34,35].…”

“…-cerium(IV) CL system is favorable for the determination of organic acids [23][24][25]32] and sulfurcontaining analytes [26][27][28][29]33], outside of amine-containing analytes. In the proposed scheme, the a-ketocarboxylic acids including oxalic acid, 2-ketoglutaric acid, 2-ketobutyric acid, and sodium pyruvate were used as models to demonstrate the feasibility of the CE-CL approach.…”
