Zk. He et al., Chemiluminescence determination of sulfur dioxide in air using tris(1,10-phenanthroline)ruthenium-KIO4 system, ANAL LETTER, 32(2), 1999, pp. 401-410
The emission produced by sulfite in its oxidation by periodate in acidic so
lution in the presence of Ru(phen)(3)(2+) is used to determine 1.0x10(-7) t
o 1.5x10(-4) mom sulfite. The limit of detection is 7x10(-10) mol/L and the
relative standard deviation is 2.3% for a 4x10(-5) mol/L sulfite solution
(n=9). The method was applied satisfactorily to the determination of sulfur
dioxide in air by using triethanolamine (TEA) as absorbent material.
