| Abstract: | A new method for removal of organic molecules from water was discussed, a low temperature plasma corona discharge was formed in water. Chemically active particles were diffused into water and the organics were oxidized. phenol was used in this experiment. The pulse corona discharge wares of the voltage and current were measured. The influence of the existence of radical scavengers on COD of the solution and the influence of pH on rate of degradation were discussed. The chromatogram of phenol solution after pulse corona discharge at absorption wavelength of 210 nm by gas chromategraphic detector was determined. |
