Abstract The report gives results of measurements of the rate of chlorine (C12) absorption into aqueous sulfite/bisulfite-S(IV)-solutions at ambient temperature using a highly characterized stirred-cell reactor. The reactor media were 9 to 10 mM S(IV) with pHs of 3.5-8.5. Experiments were performed using 20-300 ppm C12 in nitrogen (N2) or air. C12 absorption was modeled using the theory of mass transfer with chemical reaction. C12 reacts quickly with S(IV) to form chlorine and sulfate. C12 absorbtion is enhanced by increasing pH and S(IV) concentration. The rate constant for the reaction of C12 with S(IV) was too rapid to be precisely measured using the existing stirred-cell reactor, due to mass transfer limitations. However, the most probable value of the rate constant was determined to be 2 x 10 to the 9th power L/mol-s. These results are relevant to the simultaneous removal of C12, sulfur dioxide, and Hg should be possible with the injection of 1-10 ppm C12 to an existing limestone slurry scrubber. These results may also be applicable to scrubber design for removal of C12 in the pulp and paper and other industries.
