Chemical Kinetics of Manganese Catalyzed Sulfur-Dioxide Autooxidation That Occurs in the Solution Phase of Slurries

This study deals with the manganese catalyzed oxidation of bisulfite and sulfite anions by molecular oxygen in a tubular flow calorimeter. Solutions of oxygen and sulfur dioxide anions at the same pH and temperature with varying catalyst combined in an efficient Teflon mixer to form the reaction system. This inert, adiabatic, microcomputer-automated reactor used thermistors to capture the resulting temperature profiles for the kinetic determinations by the method of initial slopes. For the sodium based reaction the conditions were: T 25° 20° - 35° °C pH 4.4 - 6, 11 11 {S('4+)} 0.003 - 0.15 M/1 {O(,2)} 0.004 - 0.015 M/1 {Mn} 10 - 2000 0.05 - 10 ppm (wt).
