| Due to the occurrence of organic contamination frequently in recent years, the organophosphorus pesticides dichlorvos, as the simulated organic pollutants, was rapidly eliminated using spraying hydroxyl radical (•OH) produced by strong electric-field ionization discharge method on an aluminium flat plate about 10 cm2 in this work. The aqueous •OH solution of high concentration was produced from gaseous H2O (H2Ogas) and O2 with plasma reaction. In a condition, where pH is 6 and the initial density of dichlorvos on the simulation plane is 20 μg/cm2, when the spray density of •OH reaches 1 μg/cm2, the removal efficiency of dichlorvos can reach to 90%, and the mineralization rate is lower the removal efficiency. And the removal efficiency is proportional to the spray spraying density of hydroxyl radical.The effct of pH value on the removal efficiency was also investigated. It is found that the removal efficiency of organophosphorus pollutants decreased slowly at the beginning and then increased with the increase of pH value (from 2 to 12), and the lowest of removal rate appeared when pH value close to 7. It is contribute to removal of dichlorovs under alkaline conditions. Four factors and three levels orthogonal experiment indicated that •OH had great influence on the surface oxidation removal rapdily of organophosphorus pollutants in a short period of time. |
