%X The degradation mechanism of p-chlorophenol in the aqueous solution by pulsed high-voltage discharge plasma was explored by measuring the oxidant species generated due to the pulsed high-voltage discharge in the aqueous solution and by comparing the technique experimental results of various conditions. When oxygen was bubbled to the aqueous solution in the discharge reactor through the discharge electrode, the organic pollutants in the aqueous solution were degradated through the following steps. First, ozone was formed due to the oxygen discharge in the strong electric field. And then ozone transfered from gas bubble to the aqueous solution containing p-chlorophenol. In the aqueous solution, ozone could decompose to form ·OH radical. The ozone and ·OH radical in the aqueous solution could react with the p-chlorophenol contained in the aqueous solution. The investigation of the organic pollutant degradation mechanism in the aqueous solution could provide the theoretical base to the mathematical modeling of the organic pollutants degradation by the pulsed high-voltage discharge plasma in the aqueous solution.
