| Abstract: | The electrochemistry process to produce Fenton reagents was described. The in situ oxidation of dodecylben-zenesulphonic acid-(6)-sodium salt (DBS) with electrogenerated hydroxyl radicals was investigated. The I-V cyclic voltammograms was measured. The IR spectrogram result indicated that DBS was decomposed into small molecule compounds and inorganic molecule, such as H 2O and CO 2. So far, the degradation of the DBS was confirmed by the UV spectrogram and the chemical analysis. The COD Cr removal rate was high than 85%. |
