| Abstract: | The reduction kinetics of sodium chlorate with pyrite to produce chlorine dioxide was investigated. It was shown that selectivity of chlorate ion reduced to chlorine dioxide was over 99.7%. The reaction has been found in zero and first orders with respect to ClO3- and H+, respectively. The kinetic equation is rD=kCB, the apparent activation energy is 52.9 kJ/mol, and the reaction rate constant k=2.14x107exp(-6360/T) L/(m2.min), respectively. |
