| Abstract: | A comprehensive comparison of degradation of chlorobenzene and trichloromethane by means of ozone(O3),ultraviolet radiation(UV),aeration plus UV and the combination of ozone with UV was conducted.Further work on the mechanism of applying UV/O3 method for removing these two organics was also carried out.The concentration of Cl-as a decomposed product of chlorobenzene was determined.It is shown that after 90min,the concentration are 2.03mg/L for UV(253.7nm) and 1.80mg/L with UV(253.7nm)/O3,and after 150min ar... |
