摘要：

The emission produced by sulfite in its oxidation by periodate in acidic solution in the presence of Ru(phen)(3)(2+) is used to determine 1.0x10(-7) to 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.
