"Determination Of Sulfite In Sugar And Sulfur Dioxide In Air By Chemiluminescence Using The Ru(bipy)3(2+)-KBrO3 System"
Analyst 1998 Volume 123, Issue 10 Pages 2109-2112

Abstract: A chemiluminescence (CL) detection method for the determination of sulfite using the reaction of Ru(bipy)32+ (bipy = 2,2'-bipyridyl)-SO32--KBrO3 is described. The concentration of sulfite is proportional to the CL intensity in the range 2.5 x 10^-8-9.5 x 10^-5 mol l-1. The limit of detection is 3.8 x 10^-9 mol L-1 and the relative standard deviation is 4.6% for 5 x 10^-5 mol L-1 sulfite solution with nine repeated measurements. This method was successfully applied to the determination of sulfite in sugar and sulfur dioxide in air by using triethanolamine as the absorbent material.

Abstract: The chemiluminescence (CL) detection for the determination of sulfite using the reaction of Ru(bipy)(3)(2+)(bipy=2,2'-bipyridyl)-SO32--KIO4 is described. The concentration of sulfite is proportional to the CL intensity from 1.0 x 10^-7 to 1.0 x 10^-4 mol/L. The limit of detection is 2.0 x 10^-8 mol/L and the relative standard deviation is 4.4% for a 2 x 10^-5 mol/L sulfite solution (n = 9). This method has successfully been applied to the determination of sulfite in powdered sugar (sucrose) and of sulfur dioxide in air by using triethanolamine (TEA) as absorbent material.
