• 305 Removal of Persistent Contaminants in Water Using Nonthermal Plasma and Gas Bubbling

抄録

The decomposition of trace phenol in the solution, using a liquid-phase nonthermal plasma, which has been investigated by many researchers, results in extremely high power consumption. Therefore, we have investigated the phenol decomposition, using gas-phase plasma applied above the surface of the solution. However, the phenol decomposition was insufficient because the chemical reaction took place only at the surface of the solution. Then, gas bubbling was employed to enlarge the solution contact area, which resulted in significant improvement in terms of phenol decomposition in solution. Furthermore, the air mixed with argon (Ar) and hydrogen peroxide (H_2O_2) were investigated. The removal efficiency with air mixed with H_2O_2 bubbling was about twice as high as that with air bubbling alone, due to the generation of hydroxyl (OH) radical in solution.
