| Abstract: | Based on the catalytic of sulfite on the oxidation of potassium bromate with thionine in the medium of phosphoric acid, a determination of sulfite was established by catalytic spectropho- tometry and the experiment conditions were optimized. The linear range of the determination of sulfite is3.0×10^-6～2.2×10^-4g/mL with the detection limit of 4.9×10^-7g/mL. This method has been applied to the determination of sulfite in coking waste water with satisfactory results. |
