AB  - Flushing soils contaminated with trichloroethylene (TCE) and perchloroethylene 
      (PCE) with a permanganate (MnO4-) solution has been shown to reduce the solvent 
      content of the soil. Experiments were performed to quantify the rate at which 
      KMnO4 oxidizes aqueous solutions of PCE over a range of concentrations. In a 
      series of homogeneous reactors, aqueous phase PCE concentrations were monitored 
      over time in nine experimental trials with excess oxidant concentrations ranging 
      from 5 to 30 g/l. Analysis of the data was performed to quantify the oxidation 
      reaction order with respect to PCE and KMnO4 and the reaction rate constant. The 
      reaction between PCE and KMnO4 was determined to be first-order with respect to 
      both PCE and KMnO4 with an overall specific reaction rate coefficient of 
      2.45+/-0.65 M(-1) min(-1).
